What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

Prevent plagiarism. Run a free check.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

Writing the literature review chapter can seem pretty daunting when you’re piecing together your dissertation or thesis. As  we’ve discussed before , a good literature review needs to achieve a few very important objectives – it should:

• Demonstrate your knowledge of the research topic
• Identify the gaps in the literature and show how your research links to these
• Provide the foundation for your conceptual framework (if you have one)
• Inform your own  methodology and research design

To achieve this, your literature review needs a well-thought-out structure . Get the structure of your literature review chapter wrong and you’ll struggle to achieve these objectives. Don’t worry though – in this post, we’ll look at how to structure your literature review for maximum impact (and marks!).

But wait – is this the right time?

Deciding on the structure of your literature review should come towards the end of the literature review process – after you have collected and digested the literature, but before you start writing the chapter. 

In other words, you need to first develop a rich understanding of the literature before you even attempt to map out a structure. There’s no use trying to develop a structure before you’ve fully wrapped your head around the existing research.

Equally importantly, you need to have a structure in place before you start writing , or your literature review will most likely end up a rambling, disjointed mess. 

Importantly, don’t feel that once you’ve defined a structure you can’t iterate on it. It’s perfectly natural to adjust as you engage in the writing process. As we’ve discussed before , writing is a way of developing your thinking, so it’s quite common for your thinking to change – and therefore, for your chapter structure to change – as you write. 

Need a helping hand?

Like any other chapter in your thesis or dissertation, your literature review needs to have a clear, logical structure. At a minimum, it should have three essential components – an  introduction , a  body   and a  conclusion . 

Let’s take a closer look at each of these.

1: The Introduction Section

Just like any good introduction, the introduction section of your literature review should introduce the purpose and layout (organisation) of the chapter. In other words, your introduction needs to give the reader a taste of what’s to come, and how you’re going to lay that out. Essentially, you should provide the reader with a high-level roadmap of your chapter to give them a taste of the journey that lies ahead.

Here’s an example of the layout visualised in a literature review introduction:

Your introduction should also outline your topic (including any tricky terminology or jargon) and provide an explanation of the scope of your literature review – in other words, what you  will   and  won’t   be covering (the delimitations ). This helps ringfence your review and achieve a clear focus . The clearer and narrower your focus, the deeper you can dive into the topic (which is typically where the magic lies). 

Depending on the nature of your project, you could also present your stance or point of view at this stage. In other words, after grappling with the literature you’ll have an opinion about what the trends and concerns are in the field as well as what’s lacking. The introduction section can then present these ideas so that it is clear to examiners that you’re aware of how your research connects with existing knowledge .

2: The Body Section

The body of your literature review is the centre of your work. This is where you’ll present, analyse, evaluate and synthesise the existing research. In other words, this is where you’re going to earn (or lose) the most marks. Therefore, it’s important to carefully think about how you will organise your discussion to present it in a clear way. 

The body of your literature review should do just as the description of this chapter suggests. It should “review” the literature – in other words, identify, analyse, and synthesise it. So, when thinking about structuring your literature review, you need to think about which structural approach will provide the best “review” for your specific type of research and objectives (we’ll get to this shortly).

There are (broadly speaking)  three options  for organising your literature review.

Option 1: Chronological (according to date)

Organising the literature chronologically is one of the simplest ways to structure your literature review. You start with what was published first and work your way through the literature until you reach the work published most recently. Pretty straightforward.

The benefit of this option is that it makes it easy to discuss the developments and debates in the field as they emerged over time. Organising your literature chronologically also allows you to highlight how specific articles or pieces of work might have changed the course of the field – in other words, which research has had the most impact . Therefore, this approach is very useful when your research is aimed at understanding how the topic has unfolded over time and is often used by scholars in the field of history. That said, this approach can be utilised by anyone that wants to explore change over time .

For example , if a student of politics is investigating how the understanding of democracy has evolved over time, they could use the chronological approach to provide a narrative that demonstrates how this understanding has changed through the ages.

Here are some questions you can ask yourself to help you structure your literature review chronologically.

• What is the earliest literature published relating to this topic?
• How has the field changed over time? Why?
• What are the most recent discoveries/theories?

In some ways, chronology plays a part whichever way you decide to structure your literature review, because you will always, to a certain extent, be analysing how the literature has developed. However, with the chronological approach, the emphasis is very firmly on how the discussion has evolved over time , as opposed to how all the literature links together (which we’ll discuss next ).

Option 2: Thematic (grouped by theme)

The thematic approach to structuring a literature review means organising your literature by theme or category – for example, by independent variables (i.e. factors that have an impact on a specific outcome).

As you’ve been collecting and synthesising literature , you’ll likely have started seeing some themes or patterns emerging. You can then use these themes or patterns as a structure for your body discussion. The thematic approach is the most common approach and is useful for structuring literature reviews in most fields.

For example, if you were researching which factors contributed towards people trusting an organisation, you might find themes such as consumers’ perceptions of an organisation’s competence, benevolence and integrity. Structuring your literature review thematically would mean structuring your literature review’s body section to discuss each of these themes, one section at a time.

Here are some questions to ask yourself when structuring your literature review by themes:

• Are there any patterns that have come to light in the literature?
• What are the central themes and categories used by the researchers?
• Do I have enough evidence of these themes?

PS – you can see an example of a thematically structured literature review in our literature review sample walkthrough video here.

Option 3: Methodological

The methodological option is a way of structuring your literature review by the research methodologies used . In other words, organising your discussion based on the angle from which each piece of research was approached – for example, qualitative , quantitative or mixed  methodologies.

Structuring your literature review by methodology can be useful if you are drawing research from a variety of disciplines and are critiquing different methodologies. The point of this approach is to question  how  existing research has been conducted, as opposed to  what  the conclusions and/or findings the research were.

For example, a sociologist might centre their research around critiquing specific fieldwork practices. Their literature review will then be a summary of the fieldwork methodologies used by different studies.

Here are some questions you can ask yourself when structuring your literature review according to methodology:

• Which methodologies have been utilised in this field?
• Which methodology is the most popular (and why)?
• What are the strengths and weaknesses of the various methodologies?
• How can the existing methodologies inform my own methodology?

3: The Conclusion Section

Once you’ve completed the body section of your literature review using one of the structural approaches we discussed above, you’ll need to “wrap up” your literature review and pull all the pieces together to set the direction for the rest of your dissertation or thesis.

The conclusion is where you’ll present the key findings of your literature review. In this section, you should emphasise the research that is especially important to your research questions and highlight the gaps that exist in the literature. Based on this, you need to make it clear what you will add to the literature – in other words, justify your own research by showing how it will help fill one or more of the gaps you just identified.

Last but not least, if it’s your intention to develop a conceptual framework for your dissertation or thesis, the conclusion section is a good place to present this.

Example: Thematically Structured Review

In the video below, we unpack a literature review chapter so that you can see an example of a thematically structure review in practice.

Let’s Recap

In this article, we’ve  discussed how to structure your literature review for maximum impact. Here’s a quick recap of what  you need to keep in mind when deciding on your literature review structure:

• Just like other chapters, your literature review needs a clear introduction , body and conclusion .
• The introduction section should provide an overview of what you will discuss in your literature review.
• The body section of your literature review can be organised by chronology , theme or methodology . The right structural approach depends on what you’re trying to achieve with your research.
• The conclusion section should draw together the key findings of your literature review and link them to your research questions.

Great work. This is exactly what I was looking for and helps a lot together with your previous post on literature review. One last thing is missing: a link to a great literature chapter of an journal article (maybe with comments of the different sections in this review chapter). Do you know any great literature review chapters?

I agree with you Marin… A great piece

I agree with Marin. This would be quite helpful if you annotate a nicely structured literature from previously published research articles.

Awesome article for my research.

I thank you immensely for this wonderful guide

It is indeed thought and supportive work for the futurist researcher and students

Very educative and good time to get guide. Thank you

Great work, very insightful. Thank you.

Thanks for this wonderful presentation. My question is that do I put all the variables into a single conceptual framework or each hypothesis will have it own conceptual framework?

Thank you very much, very helpful

This is very educative and precise . Thank you very much for dropping this kind of write up .

comprehensive explanation. Help us by pasting the URL of some good “literature review” for better understanding.

great piece. thanks for the awesome explanation. it is really worth sharing. I have a little question, if anyone can help me out, which of the options in the body of literature can be best fit if you are writing an architectural thesis that deals with design?

I am doing a research on nanofluids how can l structure it?

Beautifully clear.nThank you!

Lucid! Thankyou!

Brilliant work, well understood, many thanks

I like how this was so clear with simple language 😊😊 thank you so much 😊 for these information 😊

Insightful. I was struggling to come up with a sensible literature review but this has been really helpful. Thank you!

You have given thought-provoking information about the review of the literature.

Thank you. It has made my own research better and to impart your work to students I teach

I learnt a lot from this teaching. It’s a great piece.

I am doing research on EFL teacher motivation for his/her job. How Can I structure it? Is there any detailed template, additional to this?

You are so cool! I do not think I’ve read through something like this before. So nice to find somebody with some genuine thoughts on this issue. Seriously.. thank you for starting this up. This site is one thing that is required on the internet, someone with a little originality!

I’m asked to do conceptual, theoretical and empirical literature, and i just don’t know how to structure it

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question.  That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

• Explains the background of research on a topic.
• Demonstrates why a topic is significant to a subject area.
• Discovers relationships between research studies/ideas.
• Identifies major themes, concepts, and researchers on a topic.
• Identifies critical gaps and points of disagreement.
• Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question.  The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

• Make sure your research question is not too broad or too narrow.  Is it manageable?
• Begin writing down terms that are related to your question. These will be useful for searches later.
• If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

• This may depend on your assignment.  How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search. 

Where to find databases:

• use the tabs on this guide
• Find other databases in the Nursing Information Resources web page
• More on the Medical Library web page
• ... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

• Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
• Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
• Review the abstracts of research studies carefully. This will save you time.
• Use the bibliographies and references of research studies you find to locate others.
• Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
• Ask your librarian for help at any time.
• Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

• What was the research question of the study you are reviewing? What were the authors trying to discover?
• Was the research funded by a source that could influence the findings?
• What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
• Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
• If there are conflicting studies, why do you think that is?
• How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips: 

• Review the abstracts carefully.  
• Keep careful notes so that you may track your thought processes during the research process.
• Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

Using keywords, search a library database.

Reference lists of recent articles and reviews can lead to other useful papers.

Include any studies contrary to your point of view.

Evaluate and synthesize the studies' findings and conclusions.

Note the following:

• Assumptions some or most researchers seem to make
• Methodologies, testing procedures, subjects, material tested researchers use
• Experts in the field: names/labs that are frequently referenced
• Conflicting theories, results, methodologies
• Popularity of theories and how this has/has not changed over time
• Findings that are common/contested
• Important trends in the research
• The most influential theories

Tip: If your literature review is extensive, find a large table surface, and on it place post-it notes or filing cards to organize all your findings into categories.

• Move them around if you decide that (a) they fit better under different headings, or (b) you need to establish new topic headings.
• Develop headings/subheadings that reflect the major themes and patterns you detected

Write a one or two sentence statement summarizing the conclusion you have reached about the major trends and developments you see in the research that has been conducted on your subject.

• 5 Types of Thesis Statements Learn about five different types of thesis statements to help you choose the best type for your research. There is also a downloadable PDF version.
• 5 Questions to Strengthen Your Thesis Statement Follow these five steps to strengthen your thesis statements. There is also a downloadable PDF version.

Follow the organizational structure you developed above, including the headings and subheadings you constructed.

Make certain that each section links logically to the one before and after.

Structure your sections by themes or subtopics, not by individual theorists or researchers.

• Tip: If you find that each paragraph begins with a researcher's name, it might indicate that, instead of evaluating and comparing the research literature from an analytical point of view, you have simply described what research has been done.

Prioritize analysis over description.

• For example, look at the following two passages and note that Student A merely describes the literature, whereas Student B takes a more analytical and evaluative approach by comparing and contrasting. You can also see that this evaluative approach is well signaled by linguistic markers indicating logical connections (words such as "however," "moreover") and phrases such as "substantiates the claim that," which indicate supporting evidence and Student B's ability to synthesize knowledge.

Student A: Smith (2000) concludes that personal privacy in their living quarters is the most important factor in nursing home residents' perception of their autonomy. He suggests that the physical environment in the more public spaces of the building did not have much impact on their perceptions. Neither the layout of the building nor the activities available seem to make much difference. Jones and Johnstone make the claim that the need to control one's environment is a fundamental need of life (2001), and suggest that the approach of most institutions, which is to provide total care, may be as bad as no care at all. If people have no choices or think that they have none, they become depressed.

Student B: After studying residents and staff from two intermediate care facilities in Calgary, Alberta, Smith (2000) came to the conclusion that except for the amount of personal privacy available to residents, the physical environment of these institutions had minimal if any effect on their perceptions of control (autonomy). However, French (1998) and Haroon (2000) found that availability of private areas is not the only aspect of the physical environment that determines residents' autonomy. Haroon interviewed 115 residents from 32 different nursing homes known to have different levels of autonomy (2000). It was found that physical structures, such as standardized furniture, heating that could not be individually regulated, and no possession of a house key for residents limited their feelings of independence. Moreover, Hope (2002), who interviewed 225 residents from various nursing homes, substantiates the claim that characteristics of the institutional environment such as the extent of resources in the facility, as well as its location, are features which residents have indicated as being of great importance to their independence.

• How to Integrate Critical Voice into Your Literature Review (Video)
• Look at the topic sentences of each paragraph. If you were to read only these sentences, would you find that your paper presented a clear position, logically developed, from beginning to end? The topic sentences of each paragraph should indicate the main points of your literature review.
• Make an outline of each section of the paper and decide whether you need to add information, to delete irrelevant information, or to re-structure sections.
• Read your work out loud. That way you will be better able to identify where you need punctuation marks to signal pauses or divisions within sentences, where you have made grammatical errors, or where your sentences are unclear.
• Since the purpose of a literature review is to demonstrate that the writer is familiar with the important professional literature on the chosen subject, check to make certain that you have covered all of the important, up-to-date, and pertinent texts. In the sciences and some of the social sciences it is important that your literature be quite recent; this is not so important in the humanities.
• Make certain that all of the citations and references are correct and that you are referencing in the appropriate style for your discipline. If you are uncertain which style to use, ask your professor.
• Check to make sure that you have not plagiarized either by failing to cite a source of information, or by using words quoted directly from a source. (Usually if you take three or more words directly from another source, you should put those words within quotation marks, and cite the page.)
• Text should be written in a clear and concise academic style; it should not be descriptive in nature or use the language of everyday speech.
• There should be no grammatical or spelling errors.
• Sentences should flow smoothly and logically.

How to Write a Literature Review for Research: Guide, Structure & Template Examples

Table of contents

Use our free Readability checker

A literature review is a critical analysis of published research on a particular topic. It involves reviewing and analyzing a range of sources, such as academic articles, books, and reports. Students conduct a literature review before writing a research paper or dissertation to gain an understanding of the existing knowledge and recognize areas for further exploration.

Evaluating scholarly works is a crucial aspect of academic work because it establishes the foundation for an inquiry and uncovers new information or gaps in studies. Thus, it is essential to develop and structure it correctly.  In this guide you will find:

• A detailed definition
• Elements of a good literary review
• How to do a literature review
• Examples of literature review template.

Read on to explore the structure and straightforward steps for assessing existing sources on your topic.  In case you are looking for a quick solution, consider giving our literature review services a try. 

What Is a Literature Review: Definition

Before delving further, let’s first define what is a literature review in research. As a researcher, you might need to objectively synthesize, explore, and evaluate existing studies conducted by others. A literature review helps you identify gaps or areas that require further investigation. It boils down to analyzing and making sense of a massive body of knowledge. It is crucial to be critical during the entire process as it is the most effective approach to engaging with texts. You need to objectively identify their strengths and weaknesses, and convey your positive or negative views.   In other words, literature reviews are about deducing specific sources and comparing relevant studies to find similarities and differences. This process may reveal new perspectives or offer a thorough outline for further developments in a specific field. It can also inform readers about the relevance and validity of existing documents to the statement of the problem . You conduct a lit review to get an overview of concepts surrounding your subject, keep up to date with trends in your field, and enhance your credibility. Besides, it offers a solid background for a research paper , thesis or dissertation .

What Is the Purpose of a Literature Review?

A literature review must highlight your overall knowledge of a research subject and help you develop an argument, mostly by responding to a specific question. It is not just a summary of what you have read.  Commonly, the purpose of a literature review is to help you:

• Understand and convey the current state of literature on your research topic .
• Find adequate documents on your subject to form your perspective.
• Create a framework for your paper based on research goals.
• Identify gaps in studies and develop novel research questions .
• Select appropriate methods by locating tried and tested techniques.

Note that keeping all these points in mind is important to get the most from an evaluation process when conducting the review.

Types of Literature Reviews

There are various types of literature reviews, each with specific expectations in terms of depth, structure, length, and scope. Here are the main ones:

• Stand-alone literature review. This type involves a comprehensive analysis of prior research related to a specific question. Here, your task is to evaluate and compare existing studies, identify trends, and recognize gaps, weaknesses, and controversies in the field.
• Literature review for a journal article. In this case, the analysis of literature focuses on providing background information for an inquiry being conducted. It is usually placed in an introduction or combined with the discussion of results.
• Literature review assignment. Students may be assigned a selective project to familiarize themselves with a theme and studies in their field. The intention could also be to identify gaps in the current knowledge base to suggest new questions, develop a theoretical framework in research , or determine a suitable methodology for future exploration. This type deals with a small part of research on a subject and stands as a complete work.
• Research paper literature review. The main objective here is to facilitate scholars in gathering, condensing, synthesizing, and examining current research on a specific issue. This is particularly beneficial to academics who are investigating a new area of study or seeking guidance on topics that have not yet been thoroughly explored.
• Thesis or dissertation literature review. This is a separate chapter placed after the Ph.D. thesis introduction and before the dissertation methodology section. It helps the author understand what has already been studied and what gaps exist in the current knowledge. By analyzing the existing research, a researcher can identify opportunities for further investigation and ensure that their study is original and significant.

How Long Should a Literature Review Be?

If the instructions for a task do not specify the required length of the literature review, there are some guidelines to consider. In general, it would be enough to have 20-25% of the total size of your work as an analysis part. Typically, the analysis section of the review should constitute around 20-25% of the total length of the work. However, several factors, such as the project purpose, intended audience, type, and scope, may affect how long a literature review is. For example, a dissertation usually requires an extensive literature evaluation section. The best assessments, however, are usually not less than 2 pages long.  If you are uncertain about the appropriate length, refer to the table below for guidance.

Features of a Good Literature Review

Regardless of your work’s nature, composing a good literature review is a laborious process that many students rightfully find challenging. This is because you may need to go through numerous studies and identify gaps, recognize frameworks, cite sources, and ensure coherence. Therefore, to develop a decent piece it is essential to consider the characteristics described below. The best work:

• Is more than just a list of relevant studies: you should critically examine others’ ideas and assess how they are presented.
• Considers a variety of reliable and applicable sources: a scientific literature review should demonstrate that you are familiar with relevant readings on your topic. Thus, ensure you have covered important, broad, latest, and pertinent texts. Such an approach enhances the depth of your evaluation and highlights various viewpoints.
• Demonstrates an awareness of values and theories underpinning the work: in the first place, you must understand why exactly you are conducting the evaluation. If you don’t know the purpose and function of the process, you will not write effectively.
• Relates papers to each other by comparing and contrasting them: a literature review in research moves past simple descriptions of what others have written. Rather, it entails connecting, finding differences and similarities, and interpreting concepts.
• Offers personal reactions and opinions to manuscripts: after comparing, contrasting, and critiquing others’ works, you should present your own interpretation and analysis.
• Showcases research gaps that your study will deal with and help address.
• Applies appropriate linking/transition words such as “similarly”, “however”, “also”, “contend”, “conclude”, “argue”, and “assert”: this helps you group together related notions, highlight contrasting views, and introduce others’ opinions or texts while remaining objective throughout the analysis.

What to Include in a Literature Review?

At this point, you understand the definitions, purpose, and features of a literature review. Now you need to present information effectively. Like in any other formal paper, your work must have a basic structure comprising an introduction, body, and conclusion.  But what does it look like? The layout goes beyond these sections because you must also consider how your themes and arguments will be organized.  Here is a detailed description of the three main parts of a literature review:

• Introduction Your first section should be brief, direct, and focused. Explain the main themes or topics to be analyzed, the arguments you will present, and the underlying reasons for your claims.
• Body In this section, conduct a comprehensive evaluation of the selected sources and organize them using a specific approach, such as themes or topics. Make sure to present your arguments clearly, linking them to studies that support or contradict your assessment. Remember to include viewpoints that disagree with your position to strengthen your evaluation. Cite the works of various authors you are critically analyzing, and limit the use of direct quotes. Instead, paraphrase and include references.
• Conclusion Summarize your literature review by highlighting the conclusions drawn from your analysis. You can restate gaps in knowledge, explain how your study will address them, and recommend future research needed on the topic.

Look at the example of the literature review template below to learn more.

How to Structure a Literature Review?

Once you are ready to begin writing a literature review, it is necessary to think about how you will organize information. This helps avoid the risk of your work turning into a loose sequence of summaries instead of a logical and integrated analysis.  A literature review structure should be chosen based on the style used in your body section. Here are the major approaches you can use:

• Thematic This approach involves organizing your analysis around themes, topics, or issues. It is particularly useful when focusing on a single overarching subject and enables you to highlight critical debates within sub-themes.
• Chronological Literature reviews using this format organize studies based on when they were published, typically moving from older to newer works to explore the topic's development over time. It is important to analyze sources by considering any debates and turning points that influenced the subject and offer your interpretation.
• Methodological This design focuses on the methods other researchers used. A review of literature using this layout considers the perspective from which a particular theme was examined or the procedures used to answer a specific question. It may use qualitative, quantitative, or other strategies within these two broad techniques.
• Theoretical A theoretical approach involves a systematic and critical examination of existing theories, models, and frameworks related to the research topic or question. This approach helps to establish the context, identify gaps, and provide a foundation for your own research.

How to Write a Literature Review?

If you are still wondering how to write a literature review for a research paper, thesis or dissertation, this guideline will help you get started. While you have learned about important elements such as structuring and organization, you may still need guidance on how to establish your foundation for creating your review.  The following sections provide easy-to-understand explanations on how to write a lit review. Below are 7 steps you must follow to develop a decent paper.

1. Select a Topic and Narrow It Down

As you begin reviewing literature, it is vital to get your focus correct. Depending on your field of study, the selected topic must be:

• Relevant and important Explore a crucial concern in your field so that people will be interested in your work and you will have sufficient material to base your project on.
• Interesting This is essential because learning how to write a good literature review starts with being inquisitive since you can’t investigate something that doesn’t arouse your curiosity.
• Well defined this helps you include only relevant publications to make your paper helpful.
• Narrow Your theme must be specific yet researched enough to allow for an in-depth analysis. Broad issues usually necessitate a large number of studies, which will be impossible to explore meaningfully.

2. Search for Pertinent Literature

After having selected a topic for your research literature review, you need to search for studies. As you do this research, you'll want to take note of the keywords and phrases that appear frequently in the articles. These keywords can be used to create a list of search terms that you'll use to find additional articles on your topic. To ensure that your search terms are effective, you should try to identify the most important keywords and phrases related to your topic. These might be the names of key researchers, conceptual frameworks , theories, or techniques related to your topic. Consider the headings that the documents have been tagged with and words occurring in abstracts and titles. You can then organize your phrases into blocks based on the main ideas. Once you have identified the relevant keywords for your scientific literature review, it's time to search for articles. To do this, you'll need to choose at least two credible databases to search for good articles. Popular options include:

• Google Scholar

But there may be other databases that are more appropriate for your specific topic. When searching across different databases, it's important to use a uniform search strategy. This means combining your search terms using " OR " and " AND " to create a block of related terms. You can then type this block into the basic search box or use the advanced search feature, enclosing the terms in parentheses. This makes it easier to find specific articles. For example, consider these keywords:

Since the generated results may contain irrelevant or unreliable sources, ensure that you select only dependable ones. This is a key skill to develop when conducting a literature review because it allows you to choose the best articles to support your arguments.

3. Analyze and Choose Relevant Sources

After completing your search for articles and selecting databases, it's time to review the sources and choose which ones to include in your lit review. Focus on studies that are relevant to your topic and meet any other inclusion criteria.  To determine whether an article is relevant to your project, you'll need to read it carefully and grasp the arguments presented. Take notes as you read, recording interesting facts, main points, and any thoughts you have about the article. This will help you remember which author made which arguments, your impressions of the article, and any relationships you identified between different sources. As you read, try to answer these questions:

• What is the main argument of the article?
• How does the author support their argument?
• What is the research question or objective of the study?
• What research methods were used, and were they appropriate for the research question?
• What were the main findings or results of the study?
• Were the results statistically significant, and were the conclusions supported by the data?
• Are there any limitations or weaknesses to the study that should be considered?
• Are the authors qualified to conduct this research?
• Are there any conflicts of interest or biases that may affect the study's findings?
• Is the article well-written and easy to understand?
• Are the sources cited in the article reliable and relevant to the topic?

Remember that you can only start to write your literature review after going through all your manuscripts. Therefore, creating a rough draft is essential as this gives you a general idea of the volume of available material available. While conducting a literature review, you must examine the quality of all sources critically. This typically entails using a checklist or table to evaluate aspects such as methods, results, and presentation. An example of a template to assess sources for a literature review is provided below. It contains questions and criteria that assist in locating bias, errors, or flaws. Template for Literature Evaluation

4. Group the Sources by Categories

To write a review of literature, you need to sort your sources. After reading and evaluating your articles, you should have a general idea of the main achievements, major debates, themes, trends, and outstanding issues/questions. The next step is to organize your sources into logical categories. Good research literature reviews are systematic and consistent. You may choose to arrange your sources by topic, research methodology , geographic location, or other relevant criteria. It's also helpful to use subheadings within each category to further organize your sources. As you group your sources, be sure to consider how they relate to one another and to the overall research question or topic. You may find that certain sources address multiple themes or issues. In this case you'll need to decide which category is the most appropriate for each source. Remember that the purpose of organizing your sources is to provide a clear and coherent structure for your literature review. By grouping your sources into logical categories, you make it easier for your readers to follow your arguments and understand the connections between different sources. Here is an example of how to group sources by categories.

5. Build Connection Between Your Ideas and the Literature

To complete this step of the literature review, you need to connect your research, arguments, or ideas to the texts you've gathered. Begin by using your research question to identify connections between your sources and insights into your findings. Match your key concepts with the central points in each article to establish associations between topics. Be aware that you may see differences or contradictions between readings. To ensure that you're ready to write your literature review, use your key concepts as headings in your notes to easily locate articles that address specific themes. Observe and make explicit the relationships that emerge between your arguments and the manuscripts. These connections will be useful when structuring your work and selecting the papers to include in your project.

6. Write a Literature Review

At this point, you can start a literature review because you have already synthesized relevant works in your mind and recorded the details. With that information in mind, it is time to begin composing the actual analysis and thoroughly creating each of the components of a literature review.  Initiate the process by highlighting your topic and your overall argument or view.  Just like any other academic essay , your project must be well-structured and contain an introduction, main part, and conclusion. Consider the following explanations on how to write a literature review for a dissertation, thesis, or research paper.

Literature Review Introduction

The introduction section should provide the necessary background information and clarify the purpose of your analysis.  Begin by broadly announcing the topic and providing contextual details of major concepts and terms, such as what is already known about the subject and how the field has developed. Next, provide specific and relevant information about the issue and explain why it is important or why readers should engage with your work. Finally, describe the organization, scope, and aim or highlight the key points that will be discussed. Look at the following example to see how you can write an introduction for a literature review. Literature Review Introduction Example

Lit Review Body

The body section of your literature review is where you analyze relevant studies related to your topic. It is essential to organize your analysis coherently and logically.  Identify important sub-topics and structuring them to support your arguments. Using subheadings under major themes can help to order and focus your work effectively.  While writing the body of your literature review, you should critically examine texts.  This involves recognizing gaps, points of agreement or disagreement, and key subjects.  You can structure this section chronologically, thematically, theoretically, or methodologically, depending on your research question and the nature of your sources. Remember to use reliable and accurate references to support your arguments. Consider this example: Example of a Literature Review Paper Body Section

Literature Review Conclusion

The concluding section of a literature review should show how you addressed the topic or achieved your purpose. You should then mention the major arguments you examined before identifying their implications in the broader field. Remember to recommend any applicable future research. Also, keep in mind these things when writing your literature review conclusion:

• Avoid in-text citations.
• Do not include new information.
• Highlight main ideas raised in the body paragraphs.
• Give your general view of the studies and explain your conclusions and underlying reasons.

Here is a sample literature review conclusion. Literature Review Conclusion Example

7. Proofread and Revise Your Review of Literature

Once you are done with reviewing your literature, give yourself some time off and then come back to edit it. Attend to its narrative and flow by ensuring that all parts fit together and transition smoothly from one paragraph to another. Improve any poor connections, revise to enhance clarity, or re-write sentences to eradicate construction mistakes. You can then give your scientific literature review to a colleague or friend, who is not an expert in the field, and ask their opinion about the message of your overall paper. Also, seek responses from your supervisor if possible. Use any feedback you get to better your project further. At this point, you understand how to do a lit review. Additional tips are provided below.

Literature Review Format

Besides following the aforementioned steps, you must also consider how to format a literature review. Be sure to check with your institution or target journal about style guidelines and the specific rules of your work’s layout.  Each style has instructions regarding the major sections, in-text citations, and a literature reference page.  For example, an APA paper format is based on an “author-date” approach, in which the author’s name and publication year are cited inside the document. A reference list is included on your paper’s last page. APA literature review format is dominant in the sciences, psychology, and education fields.  In contrast, an MLA format paper follows a “researcher-page number” style accompanied by works cited page, which is common in the humanities.  A Chicago style paper requires footnotes or endnotes with a bibliography section for all sources. It is mostly used in fine arts, history, and business disciplines.

Literature Review Examples

At this point, you are ready to start writing your review. Before proceeding, it is advisable to consider an example of literature review in a research paper, thesis or dissertation in your field. Thoroughly read the samples you find to get familiar with aspects such as organization, argument presentation, and referencing sources correctly. This is an effective way of learning ways of framing and structuring your work. Additionally, going through how to write a literature review example helps you understand what is expected in this task. Also, when reading these samples, pay attention to the academic language used.

Tips on Writing a Literature Review in Research

Now that you have a well-rounded idea about how to write a literature review, read the recommendation described here as they remind you of essential points. Before proceeding, remember that you should include sources that are associated with your work directly. This helps you avoid frustrating and distracting readers or making them lose sight of your purpose. Also, once you start writing your review, stick to the previously created outline and keep these tips in mind:

• Analyze Do not just list studies, rather, examine them critically to find similarities, differences, relationships, or contradictions.
• Time management Take your time to select a topic, gather literature, evaluate, read, and write. The last part should take about half of your time, while the remainder is for the other tasks.
• Revise Anticipate revising countless times before delivering a final version.
• Presentation A literature review in a research paper, thesis or dissertation must be specific and provide concrete examples. For example, rather than “this” use “this result”. First-person references should be avoided because they signal unsupported arguments. Everything written should have a reason. Also, use short paragraphs as they are easier to read. Additionally, structure your work with headings, subheadings, and subsections to make it flow.
• Paraphrase Avoid relying too much on quoting directly from sources or one researcher. Rather, paraphrase and compare authors between themselves and with your ideas.
• References Give credit to every outside idea or language by citing their work in your paper.

FAQ About Literature Reviews

1. what is a literature review in a research paper.

The literature review of a research paper is a type of academic essay that analyzes and evaluates previous or existing studies on a topic. It aims to survey readings, synthesize, and digest the obtained information. It also critically explores the data by identifying gaps in knowledge, demonstrating limitations in manuscripts, examining contradictions, and determining areas for additional research. The final piece is presented logically.

2. Where does a literature review go in a research paper?

A literature review generally comes after an introduction and before the methodology chapter of dissertations. Here, it is used to analyze relevant scholarship about a topic, ground your research paper in a specific field, and inform your data collection methods and analysis procedures.

3. How to start a literature review?

Start a literature review by describing the background of what you will analyze in your body paragraphs. There is no need to be comprehensive here. Rather, show that you clearly understand your paper’s scope. In particular, begin by conveying the established ideas and knowledge on the subject being explored to your audience.

4. What is the difference between a literature review and an annotated bibliography?

The main difference between the two is that literature reviews focus on providing an overview and analysis of existing research on a particular theme. They aim to identify the strengths and weaknesses of arguments and draw conclusions. In contrast, the purpose of an annotated bibliography is to collect sources for a specific project and offer summaries of what they are about.

5. What is the importance of a literature review?

A literature review is important because:

• It establishes a rapport with your readers They will trust you because you have examined and analyzed facts appropriately.
• Helps researchers deliver original work The entire process of conducting the assessment assists you to evade repeating something done by someone else.
• It improves your research focus Synthesizing and analyzing studies can guide and shape your investigation in new directions by providing novel insights and views on a theme.

The concentration of carbon emissions has been increasing throughout the years. The amount was 290 ppm before the industrial revolution but rose to 450 ppm afterward (Block, 2019, Wbeltz, 2020). These changes will affect the global climate significantly by influencing mean temperatures and precipitation levels. In turn, this will put pressure on global agricultural production and affect the growth speed, crop quality, and yield of staple foods like wheat (Wbeltz, 2020). Since over 90% of people worldwide depend on this crop, it must survive any climate changes. Thus, the purpose of this review is to evaluate how carbon emissions will affect global wheat production and identify any mitigation measures. The paper will explore wheat growth, yield, and quality in the face of elevated carbon levels.

Various studies show that elevated carbon emissions result in increased crop growth. Adams (2018) attributes this to improved photosynthesis in leaves when exposed to high carbon levels in the air. Other studies argue that carbon enriches crops, accelerates and amplifies their productivity, and causes improved growth (Hog, 2020). In an experimental study, Li (2019) compared crop growth under high carbon conditions and found that a 500 ppm level enhances growth by nearly 8%. Nevertheless, high carbon levels also result in other effects such as high temperatures (Daley, 2019). In turn, this leads to short growth periods or cycles. Thus, an increase in temperature while accelerating the time for growth adversely affects crop quality (Adams, 2020).

The review aimed to explore the effect of elevated carbon levels on global wheat production. Assessments of effects on the crop’s growth, yield, and quality were conducted to understand how changes in climate due to increasing carbon emissions will affect global agriculture. Findings demonstrate a definite impact of these changes on the aforementioned aspects. In particular, elevated carbon levels lead to enhanced growth, shorter growth cycle, and low and poor quality yields. It is suggested that future studies should further explore the role of other factors such as soil health and fertilizer use in explaining these effects because modern agricultural techniques are considered to harm soil quality.

A Step-by-Step Guide to Writing a Stellar Literature Review (with Help from AI)

Table of contents

Aren’t all of us mini versions of Sherlock Holmes when browsing data and archives for a research piece? As we go through the process, a comprehensive literature review is an essential toolkit to make your research shine.

A literature review consists of scholarly sources that validate the content. Its primary objective is to offer a concise summary of the research and to let you explore relevant theories and methodologies. Through this review, you can identify gaps in the existing research and bridge them with your contribution. 

The real challenge is how to write an excellent literature review. Let’s learn.

What is the purpose of a literature review?

A literature review is an introduction to your research. It helps you put your perspective to the table, along with a summary of the theme.

What does my literature review communicate?

• Explanation of your research: how the information was collected, the research method, the justification of the chosen data sources, and an overview of the data analysis.
• Framework: the journey from where the concept began and how it is presented.
• Connects the previous and current research: 

It presents the broader scope of your research by connecting it to the existing data and debates and underlining how your content fits the prevailing studies. 

In an era of information overload, a literature review must be well-structured. 

Let’s learn all about the structure and style of a literature review that’ll help you strengthen your research.

Literature review– structure and style

Begin with a question and end it with the solution– the key to structuring a literature review. It resembles an essay’s format, with the first paragraph introducing the readers to the topic and the following explaining the research in-depth.

The conclusion reiterates the question and summarizes the overall insights of your research. There’s no word count restriction. —it depends on the type of research. For example, a dissertation demands lengthy work, whereas a short paper needs a few pages. 

In a literature review, maintaining high quality is vital, with a focus on academic writing style. Informal language should be avoided in favor of a more formal tone. 

The content avoids contractions, clearly differentiating between previous and current research through the use of past and present tense. Wordtune assists in establishing a formal tone, enhancing your work with pertinent suggestions. This AI-powered tool ensures your writing remains genuine, lucid, and engaging. 

The option of refining the tonality offers multiple possibilities for rephrasing a single sentence. Thus, pick the best and keep writing.

Your friendly step-by-step guide to writing a literary review (with help from AI)

Do you find it challenging to begin the literature review? Don’t worry! We’re here to get you started with our step-by-step guide.

1. Narrow down the research scope

Simply begin with the question: What am I answering through my research?

Whether it’s cooking or painting, the real challenge is the prep-up for it rather than performing the task. Once you’re done, it smoothly progresses. Similarly, for your literature review, prepare the groundwork by narrowing down the research scope.

Browse and scoop out relevant data inclining well with your research. While you can’t cover every aspect of your research, pick a topic that isn’t too narrow nor too broad to keep your literature review well-balanced. 

2. Hunt relevant literature

The next question: Does this data align with the issue I’m trying to address?

As you review sources of information, hunt out the best ones. Determine which findings help in offering a focused insight on your topic. The best way to pick primary sources is to opt for the ones featured in reliable publications. You can also choose secondary sources from other researchers from a reasonable time frame and a relevant background.

For example, if your research focuses on the Historical Architecture of 18th-century Europe, the first-hand accounts and surveys from the past would hold more weight than the new-age publications. 

3. Observe the themes and patterns in sources

Next comes: What is the core viewpoint in most of the research? Has it stayed constant over time, or have the authors differed in their points of view?

Ensure to scoop out the essential aspects of what each source represents. Once you have collected all this information, combine it and add your interpretations at the end. This process is known as synthesis.

Synthesize ideas by combining arguments, findings and forming your new version.

4. Generate an outline

The next question: How can I organize my review effectively? When navigating multiple data sources, you must have noticed a structure throughout the research. Develop an outline to make the process easier. An outline is a skeletal format of the review, helping you connect the information more strategically.

Here are the three different ways to organize an outline– Chronologically, Thematically, or by Methodology.You can develop the outline chronologically, starting from the older sources and leading to the latest pieces. Another way of organizing is to thematically divide the sections and discuss each under the designated sub-heading.

You can even organize it per the research methods used by the respective authors. The choice of outline depends on the subject. For example, in the case of a science paper, you can divide the information into sections like introduction, types of equipment, method, procedure, findings, etc. In contrast, it’s best to present it in divisions based on timelines like Ancient, Middle Ages, Industrial revolutions, etc., for a history paper.

If you’re confused about how to structure the data, work with Wordtune. 

With the Generate with AI feature, you can mention your research topic and let Wordtune curate a comprehensive outline for your study.

Having a precise prompt is the key to getting the best results.

5. Start filling!

Your next question must be: Am I ready to compose all the parts of the literature review?

Once you’re ready with the basic outline and relevant sources, start filling in the data. Go for an introductory paragraph first to ensure your readers understand the topic and how you will present it. Ensure you clearly explain the section in the first sentence.

However, if beginning from the first paragraph seems intimidating, don’t worry! Add the main body content to the sub-headings, then jump to the introduction. 

Add headings wherever possible to make it more straightforward and guide your readers logically through different sources. Lastly, conclude your study by presenting a key takeaway and summarizing your findings. To make your task easier, work with Wordtune. It helps align your content with the desired tone and refine the structure.

6. Give attention to detail and edit

The last question: Am I satisfied with the language and content written in the literature review? Is it easy to understand?

Once you’re done writing the first draft of a literature review, it’s time to refine it. Take time between writing and reading the draft to ensure a fresh perspective. It makes it easier to spot errors when you disconnect from the content for some time. Start by looking at the document from a bird's eye to ensure the formatting and structure are in order. 

After reviewing the content format, you must thoroughly check your work for grammar, spelling, and punctuation. One of the best approaches to editing and proofreading is to use Wordtune . It helps simplify complex sentences, enhance the content quality, and gain prowess over the tonality.

The dos and don’ts of writing a literature review

Writing a stellar literature review requires following a few dos and don'ts. Just like Sherlock Holmes would never overlook a hint, you must pay attention to every minute detail while writing a perfect narrative. To help you write, below are some dos and don'ts to remember.

Composing a literature review demands a holistic research summary, each part exhibiting your understanding and approach. As you write the content, make sure to cover the following points:

• Keep a historical background of the field of research. Highlight the relevant relation between the old studies and your new research.
• Discuss the core issue, question, and debate of your topic.
• Theories lay the foundation of research. While you’re writing a literature review, make sure to add relevant concepts and ideas to support your statements.
• Another critical thing to keep in mind is to define complex terminologies. It helps the readers understand the content with better clarity. 

Examples of comprehensive literature reviews

Aren’t good examples the best way to understand a subject? Let’s look into a few examples of literature reviews and analyze what makes them well-written.

1. Critical Thinking and Transferability: A Review of the Literature (Gwendolyn Reece)

An overview of scholarly sources is included in the literature review, which explores critical thinking in American education. The introduction stating the subject’s importance makes it a winning literature review. Following the introduction is a well-defined purpose that highlights the importance of research.

As one keeps reading, there is more clarity on the pros and cons of the research. By dividing information into parts with relevant subheadings, the author breaks a lengthy literature review into manageable chunks, defining the overall structure.

Along with other studies and presented perspectives, the author also expresses her opinion. It is presented with minimal usage of ‘I,’ keeping it person-poised yet general. Toward the conclusion, the author again offers an overview of the study. A summary is further strengthened by presenting suggestions for future research as well. 

2. The Use of Technology in English Language Learning: A Literature Review

This literature review is thematically organized on how technology affects language acquisition. The study begins with an introduction to the topic with well-cited sources. It presents the views of different studies to help readers get a sense of different perspectives. After giving these perspectives, the author offers a personalized opinion.

One of the critical aspects that makes this a good literature review is a dedicated paragraph for definitions. It helps readers proceed further with a clear understanding of the crucial terminologies. There’s a comparison of the modern and previous studies and approaches to give an overall picture of the research.

Once the main body is composed, the author integrates recommendations for action-based tips. Thus, the literature review isn’t just summarizing the sources but offering actions relevant to the topics. Finally, the concluding paragraph has a brief overview with key takeaways.

15 Literature Review Examples

Literature reviews are a necessary step in a research process and often required when writing your research proposal . They involve gathering, analyzing, and evaluating existing knowledge about a topic in order to find gaps in the literature where future studies will be needed.

Ideally, once you have completed your literature review, you will be able to identify how your research project can build upon and extend existing knowledge in your area of study.

Generally, for my undergraduate research students, I recommend a narrative review, where themes can be generated in order for the students to develop sufficient understanding of the topic so they can build upon the themes using unique methods or novel research questions.

If you’re in the process of writing a literature review, I have developed a literature review template for you to use – it’s a huge time-saver and walks you through how to write a literature review step-by-step:

Literature Review Examples

For the following types of literature review, I present an explanation and overview of the type, followed by links to some real-life literature reviews on the topics.

1. Narrative Review Examples

Also known as a traditional literature review, the narrative review provides a broad overview of the studies done on a particular topic.

It often includes both qualitative and quantitative studies and may cover a wide range of years.

The narrative review’s purpose is to identify commonalities, gaps, and contradictions in the literature .

I recommend to my students that they should gather their studies together, take notes on each study, then try to group them by themes that form the basis for the review (see my step-by-step instructions at the end of the article).

Example Study

Title: Communication in healthcare: a narrative review of the literature and practical recommendations

Citation: Vermeir, P., Vandijck, D., Degroote, S., Peleman, R., Verhaeghe, R., Mortier, E., … & Vogelaers, D. (2015). Communication in healthcare: a narrative review of the literature and practical recommendations. International journal of clinical practice , 69 (11), 1257-1267.

Source: https://onlinelibrary.wiley.com/doi/pdf/10.1111/ijcp.12686  

Overview: This narrative review analyzed themes emerging from 69 articles about communication in healthcare contexts. Five key themes were found in the literature: poor communication can lead to various negative outcomes, discontinuity of care, compromise of patient safety, patient dissatisfaction, and inefficient use of resources. After presenting the key themes, the authors recommend that practitioners need to approach healthcare communication in a more structured way, such as by ensuring there is a clear understanding of who is in charge of ensuring effective communication in clinical settings.

• A Narrative Review of School-Based Physical Activity for Enhancing Cognition and Learning (Mavilidi et al., 2018) – read here
• A narrative review on burnout experienced by medical students and residents (Dyrbye & Shanafelt, 2015) – read here

2. Systematic Review Examples

This type of literature review is more structured and rigorous than a narrative review. It involves a detailed and comprehensive plan and search strategy derived from a set of specified research questions.

The key way you’d know a systematic review compared to a narrative review is in the methodology: the systematic review will likely have a very clear criteria for how the studies were collected, and clear explanations of exclusion/inclusion criteria. 

The goal is to gather the maximum amount of valid literature on the topic, filter out invalid or low-quality reviews, and minimize bias. Ideally, this will provide more reliable findings, leading to higher-quality conclusions and recommendations for further research.

You may note from the examples below that the ‘method’ sections in systematic reviews tend to be much more explicit, often noting rigid inclusion/exclusion criteria and exact keywords used in searches.

Title: The importance of food naturalness for consumers: Results of a systematic review  

Citation: Roman, S., Sánchez-Siles, L. M., & Siegrist, M. (2017). The importance of food naturalness for consumers: Results of a systematic review. Trends in food science & technology , 67 , 44-57.

Source: https://www.sciencedirect.com/science/article/pii/S092422441730122X  

Overview: This systematic review included 72 studies of food naturalness to explore trends in the literature about its importance for consumers. Keywords used in the data search included: food, naturalness, natural content, and natural ingredients. Studies were included if they examined consumers’ preference for food naturalness and contained empirical data. The authors found that the literature lacks clarity about how naturalness is defined and measured, but also found that food consumption is significantly influenced by perceived naturalness of goods.

3. Meta-analysis

This is a type of systematic review that uses statistical methods to combine and summarize the results of several studies.

Due to its robust methodology, a meta-analysis is often considered the ‘gold standard’ of secondary research , as it provides a more precise estimate of a treatment effect than any individual study contributing to the pooled analysis.

Furthermore, by aggregating data from a range of studies, a meta-analysis can identify patterns, disagreements, or other interesting relationships that may have been hidden in individual studies.

This helps to enhance the generalizability of findings, making the conclusions drawn from a meta-analysis particularly powerful and informative for policy and practice.

Title: Cholesterol and Alzheimer’s Disease Risk: A Meta-Meta-Analysis

Citation: Sáiz-Vazquez, O., Puente-Martínez, A., Ubillos-Landa, S., Pacheco-Bonrostro, J., & Santabárbara, J. (2020). Cholesterol and Alzheimer’s disease risk: a meta-meta-analysis. Brain sciences, 10(6), 386.

Source: https://doi.org/10.3390/brainsci10060386  

O verview: This study examines the relationship between cholesterol and Alzheimer’s disease (AD). Researchers conducted a systematic search of meta-analyses and reviewed several databases, collecting 100 primary studies and five meta-analyses to analyze the connection between cholesterol and Alzheimer’s disease. They find that the literature compellingly demonstrates that low-density lipoprotein cholesterol (LDL-C) levels significantly influence the development of Alzheimer’s disease.

• A meta-analysis of factors related to recycling (Geiger et al., 2019) – read here
• Stress management interventions for police officers and recruits (Patterson, Chung & Swan, 2014) – read here

Other Types of Reviews

• Scoping Review: This type of review is used to map the key concepts underpinning a research area and the main sources and types of evidence available. It can be undertaken as stand-alone projects in their own right, or as a precursor to a systematic review.
• Rapid Review: This type of review accelerates the systematic review process in order to produce information in a timely manner. This is achieved by simplifying or omitting stages of the systematic review process.
• Integrative Review: This review method is more inclusive than others, allowing for the simultaneous inclusion of experimental and non-experimental research. The goal is to more comprehensively understand a particular phenomenon.
• Critical Review: This is similar to a narrative review but requires a robust understanding of both the subject and the existing literature. In a critical review, the reviewer not only summarizes the existing literature, but also evaluates its strengths and weaknesses. This is common in the social sciences and humanities .
• State-of-the-Art Review: This considers the current level of advancement in a field or topic and makes recommendations for future research directions. This type of review is common in technological and scientific fields but can be applied to any discipline.

How to Write a Narrative Review (Tips for Undergrad Students)

Most undergraduate students conducting a capstone research project will be writing narrative reviews. Below is a five-step process for conducting a simple review of the literature for your project.

• Search for Relevant Literature: Use scholarly databases related to your field of study, provided by your university library, along with appropriate search terms to identify key scholarly articles that have been published on your topic.
• Evaluate and Select Sources: Filter the source list by selecting studies that are directly relevant and of sufficient quality, considering factors like credibility , objectivity, accuracy, and validity.
• Analyze and Synthesize: Review each source and summarize the main arguments  in one paragraph (or more, for postgrad). Keep these summaries in a table.
• Identify Themes: With all studies summarized, group studies that share common themes, such as studies that have similar findings or methodologies.
• Write the Review: Write your review based upon the themes or subtopics you have identified. Give a thorough overview of each theme, integrating source data, and conclude with a summary of the current state of knowledge then suggestions for future research based upon your evaluation of what is lacking in the literature.

Literature reviews don’t have to be as scary as they seem. Yes, they are difficult and require a strong degree of comprehension of academic studies. But it can be feasibly done through following a structured approach to data collection and analysis. With my undergraduate research students (who tend to conduct small-scale qualitative studies ), I encourage them to conduct a narrative literature review whereby they can identify key themes in the literature. Within each theme, students can critique key studies and their strengths and limitations , in order to get a lay of the land and come to a point where they can identify ways to contribute new insights to the existing academic conversation on their topic.

How to write a strong literature review

A literature review is a summary of the current research on a topic. It gives an overview of previous research and presents a rationale for your own study. A literature review is not just a list of references; it should be organized with an explicit purpose statement, thesis statement, and an outline of what will be discussed in each section.

1. Narrow your topic and select papers accordingly.

It’s important to start out with a clear idea of what you want to accomplish with your literature review. If you’re writing a paper on the effects of climate change on animal populations, for example, you’ll need to find research that has investigated those effects.

The first step in writing a literature review is to narrow your topic and select papers accordingly. For example, if you are writing about the effects of stress on cardiovascular disease, you would start by narrowing your topic to just cardiovascular disease, or narrowing it further to just heart disease. You could also narrow using subtopics like “the effects of stress on cardiovascular disease in men” or “the effects of stress on cardiovascular disease in women.” You can then go through your list and select papers that relate to those topics.

2. Search for literature.

There are many different databases available online that contain scholarly articles and other types of academic writing—you just have to know where to look! You should also search through any print indexes or journals that are relevant to your topic.

3. Read the selected articles thoroughly and evaluate them.

After you’ve found some sources that seem like they might be relevant, make sure you read them carefully and critically evaluate them before deciding whether or not they’re worth including in your paper. Look at their purpose statement(s) and introduction; read through the paragraphs carefully; consider what conclusions have been made by their authors; etc.

Make sure that they are relevant to your subject matter and that they are published within the past five years (or whatever timeframe is appropriate for your paper). Read the selected articles thoroughly and evaluate them critically by asking yourself questions such as:

• Did this article help me understand my topic more clearly?
• Did this article introduce me to new concepts that I did not know about before?
• Did this article provide any new evidence or information that will help me develop my own argument?

If the answer to these questions is yes, then keep reading! If not, move on. You don’t need every piece of information from every article

4. Organise the selected papers by looking for patterns and by developing subtopics

• “The purpose of this paper is to examine the effectiveness of [research method] in testing [hypothesis]. “
• “The purpose of this paper is to investigate the relationship between [independent variable] and [dependent variable].”
• a) It is well-organized, with sections clearly marked and subheadings used where necessary
• b) It includes direct quotes from relevant sources as well as summaries of those sources
• c) It has no spelling or grammatical errors – use our services at The Page Doctor for the final check

Mastering your literature review with ai: a step-by-step guide.

Article created from: https://youtu.be/wz8lg_3j3Ok?si=LvI1NXbMYu3J6SYi

When embarking on the journey of writing a literature review, the process may seem daunting at first. However, with the advent of AI tools, researchers can now navigate through this task more efficiently. This article will guide you through the steps of utilizing AI to structure, research, and draft your literature review, making the process not only manageable but also engaging.

Starting with a Structure

The first step in constructing a literature review is to develop a preliminary structure. AI chatbots like ChatGPT can provide a basic structure tailored to your topic. For instance, if your review is on organic photovoltaic devices, ChatGPT can suggest a structure that includes an introduction, background, advances in materials and technology, and sections on performance and efficiency. This structure serves as a skeleton to organize your ideas and can be modified as your research progresses.

Finding Literature

Once the structure is in place, the next step is to fill it with relevant literature. This involves searching for and collecting papers that support each section of your review. Tools like Elicit , which specialize in finding academic papers, can help you identify recent studies and seminal works in your field. When selecting literature, focus on the most up-to-date information to ensure your review reflects the current state of research.

Organizing References

As you collect papers, it's crucial to organize your references efficiently. Reference management tools like Mendeley (MLA) can streamline this process. These tools not only store your references but can also automatically add PDFs to your library when you upload them to a designated folder. Keeping PDFs organized in a separate folder on your computer is also advisable, as it facilitates easy access to the full texts of the papers you're referencing.

Analyzing Documents with AI

Doc Analyzer , an AI tool, is invaluable for extracting key information from the documents you've collected. By uploading your papers to Doc Analyzer and creating labels for different sections of your literature review, you can interact with the AI to get specific insights. For example, if you're investigating the basic principles of organic photovoltaic devices, Doc Analyzer can provide a concise summary of the relevant points, complete with references to the specific pages where the information is found. This feature is particularly useful for synthesizing information across multiple sources.

The Importance of Reading and Note-taking

While AI tools significantly aid in organizing and summarizing literature, it's imperative to read the papers yourself. As you go through each document, take detailed notes under the corresponding sections in your draft review. This not only helps in understanding the material but also in critically evaluating the literature to determine its relevance and significance to your review.

Leveraging AI for Efficiency and Insights

AI tools like ChatGPT and Doc Analyzer not only make the literature review process more efficient but also enable a deeper analysis of the collected literature. By automating the initial structuring and organization of literature, and providing tools for detailed analysis, these AI solutions allow researchers to focus on synthesizing insights and crafting a comprehensive review.

Remember, while AI can streamline many aspects of writing a literature review, the critical evaluation and synthesis of the literature remain inherently human tasks. Engaging deeply with your topic and the literature ensures that your review is not only comprehensive but also insightful.

Embrace the power of AI in your research journey, but also remember the value of your unique perspective and analytical skills in contributing to the academic discourse.
