Research Gap

Research Gap

Definition:

Research gap refers to an area or topic within a field of study that has not yet been extensively researched or is yet to be explored. It is a question, problem or issue that has not been addressed or resolved by previous research.

How to Identify Research Gap

Identifying a research gap is an essential step in conducting research that adds value and contributes to the existing body of knowledge. Research gap requires critical thinking, creativity, and a thorough understanding of the existing literature . It is an iterative process that may require revisiting and refining your research questions and ideas multiple times.

Here are some steps that can help you identify a research gap:

  • Review existing literature: Conduct a thorough review of the existing literature in your research area. This will help you identify what has already been studied and what gaps still exist.
  • Identify a research problem: Identify a specific research problem or question that you want to address.
  • Analyze existing research: Analyze the existing research related to your research problem. This will help you identify areas that have not been studied, inconsistencies in the findings, or limitations of the previous research.
  • Brainstorm potential research ideas : Based on your analysis, brainstorm potential research ideas that address the identified gaps.
  • Consult with experts: Consult with experts in your research area to get their opinions on potential research ideas and to identify any additional gaps that you may have missed.
  • Refine research questions: Refine your research questions and hypotheses based on the identified gaps and potential research ideas.
  • Develop a research proposal: Develop a research proposal that outlines your research questions, objectives, and methods to address the identified research gap.

Types of Research Gap

There are different types of research gaps that can be identified, and each type is associated with a specific situation or problem. Here are the main types of research gaps and their explanations:

Theoretical Gap

This type of research gap refers to a lack of theoretical understanding or knowledge in a particular area. It can occur when there is a discrepancy between existing theories and empirical evidence or when there is no theory that can explain a particular phenomenon. Identifying theoretical gaps can lead to the development of new theories or the refinement of existing ones.

Empirical Gap

An empirical gap occurs when there is a lack of empirical evidence or data in a particular area. It can happen when there is a lack of research on a specific topic or when existing research is inadequate or inconclusive. Identifying empirical gaps can lead to the development of new research studies to collect data or the refinement of existing research methods to improve the quality of data collected.

Methodological Gap

This type of research gap refers to a lack of appropriate research methods or techniques to answer a research question. It can occur when existing methods are inadequate, outdated, or inappropriate for the research question. Identifying methodological gaps can lead to the development of new research methods or the modification of existing ones to better address the research question.

Practical Gap

A practical gap occurs when there is a lack of practical applications or implementation of research findings. It can occur when research findings are not implemented due to financial, political, or social constraints. Identifying practical gaps can lead to the development of strategies for the effective implementation of research findings in practice.

Knowledge Gap

This type of research gap occurs when there is a lack of knowledge or information on a particular topic. It can happen when a new area of research is emerging, or when research is conducted in a different context or population. Identifying knowledge gaps can lead to the development of new research studies or the extension of existing research to fill the gap.

Examples of Research Gap

Here are some examples of research gaps that researchers might identify:

  • Theoretical Gap Example : In the field of psychology, there might be a theoretical gap related to the lack of understanding of the relationship between social media use and mental health. Although there is existing research on the topic, there might be a lack of consensus on the mechanisms that link social media use to mental health outcomes.
  • Empirical Gap Example : In the field of environmental science, there might be an empirical gap related to the lack of data on the long-term effects of climate change on biodiversity in specific regions. Although there might be some studies on the topic, there might be a lack of data on the long-term effects of climate change on specific species or ecosystems.
  • Methodological Gap Example : In the field of education, there might be a methodological gap related to the lack of appropriate research methods to assess the impact of online learning on student outcomes. Although there might be some studies on the topic, existing research methods might not be appropriate to assess the complex relationships between online learning and student outcomes.
  • Practical Gap Example: In the field of healthcare, there might be a practical gap related to the lack of effective strategies to implement evidence-based practices in clinical settings. Although there might be existing research on the effectiveness of certain practices, they might not be implemented in practice due to various barriers, such as financial constraints or lack of resources.
  • Knowledge Gap Example: In the field of anthropology, there might be a knowledge gap related to the lack of understanding of the cultural practices of indigenous communities in certain regions. Although there might be some research on the topic, there might be a lack of knowledge about specific cultural practices or beliefs that are unique to those communities.

Examples of Research Gap In Literature Review, Thesis, and Research Paper might be:

  • Literature review : A literature review on the topic of machine learning and healthcare might identify a research gap in the lack of studies that investigate the use of machine learning for early detection of rare diseases.
  • Thesis : A thesis on the topic of cybersecurity might identify a research gap in the lack of studies that investigate the effectiveness of artificial intelligence in detecting and preventing cyber attacks.
  • Research paper : A research paper on the topic of natural language processing might identify a research gap in the lack of studies that investigate the use of natural language processing techniques for sentiment analysis in non-English languages.

How to Write Research Gap

By following these steps, you can effectively write about research gaps in your paper and clearly articulate the contribution that your study will make to the existing body of knowledge.

Here are some steps to follow when writing about research gaps in your paper:

  • Identify the research question : Before writing about research gaps, you need to identify your research question or problem. This will help you to understand the scope of your research and identify areas where additional research is needed.
  • Review the literature: Conduct a thorough review of the literature related to your research question. This will help you to identify the current state of knowledge in the field and the gaps that exist.
  • Identify the research gap: Based on your review of the literature, identify the specific research gap that your study will address. This could be a theoretical, empirical, methodological, practical, or knowledge gap.
  • Provide evidence: Provide evidence to support your claim that the research gap exists. This could include a summary of the existing literature, a discussion of the limitations of previous studies, or an analysis of the current state of knowledge in the field.
  • Explain the importance: Explain why it is important to fill the research gap. This could include a discussion of the potential implications of filling the gap, the significance of the research for the field, or the potential benefits to society.
  • State your research objectives: State your research objectives, which should be aligned with the research gap you have identified. This will help you to clearly articulate the purpose of your study and how it will address the research gap.

Importance of Research Gap

The importance of research gaps can be summarized as follows:

  • Advancing knowledge: Identifying research gaps is crucial for advancing knowledge in a particular field. By identifying areas where additional research is needed, researchers can fill gaps in the existing body of knowledge and contribute to the development of new theories and practices.
  • Guiding research: Research gaps can guide researchers in designing studies that fill those gaps. By identifying research gaps, researchers can develop research questions and objectives that are aligned with the needs of the field and contribute to the development of new knowledge.
  • Enhancing research quality: By identifying research gaps, researchers can avoid duplicating previous research and instead focus on developing innovative research that fills gaps in the existing body of knowledge. This can lead to more impactful research and higher-quality research outputs.
  • Informing policy and practice: Research gaps can inform policy and practice by highlighting areas where additional research is needed to inform decision-making. By filling research gaps, researchers can provide evidence-based recommendations that have the potential to improve policy and practice in a particular field.

Applications of Research Gap

Here are some potential applications of research gap:

  • Informing research priorities: Research gaps can help guide research funding agencies and researchers to prioritize research areas that require more attention and resources.
  • Identifying practical implications: Identifying gaps in knowledge can help identify practical applications of research that are still unexplored or underdeveloped.
  • Stimulating innovation: Research gaps can encourage innovation and the development of new approaches or methodologies to address unexplored areas.
  • Improving policy-making: Research gaps can inform policy-making decisions by highlighting areas where more research is needed to make informed policy decisions.
  • Enhancing academic discourse: Research gaps can lead to new and constructive debates and discussions within academic communities, leading to more robust and comprehensive research.

Advantages of Research Gap

Here are some of the advantages of research gap:

  • Identifies new research opportunities: Identifying research gaps can help researchers identify areas that require further exploration, which can lead to new research opportunities.
  • Improves the quality of research: By identifying gaps in current research, researchers can focus their efforts on addressing unanswered questions, which can improve the overall quality of research.
  • Enhances the relevance of research: Research that addresses existing gaps can have significant implications for the development of theories, policies, and practices, and can therefore increase the relevance and impact of research.
  • Helps avoid duplication of effort: Identifying existing research can help researchers avoid duplicating efforts, saving time and resources.
  • Helps to refine research questions: Research gaps can help researchers refine their research questions, making them more focused and relevant to the needs of the field.
  • Promotes collaboration: By identifying areas of research that require further investigation, researchers can collaborate with others to conduct research that addresses these gaps, which can lead to more comprehensive and impactful research outcomes.

Disadvantages of Research Gap

While research gaps can be advantageous, there are also some potential disadvantages that should be considered:

  • Difficulty in identifying gaps: Identifying gaps in existing research can be challenging, particularly in fields where there is a large volume of research or where research findings are scattered across different disciplines.
  • Lack of funding: Addressing research gaps may require significant resources, and researchers may struggle to secure funding for their work if it is perceived as too risky or uncertain.
  • Time-consuming: Conducting research to address gaps can be time-consuming, particularly if the research involves collecting new data or developing new methods.
  • Risk of oversimplification: Addressing research gaps may require researchers to simplify complex problems, which can lead to oversimplification and a failure to capture the complexity of the issues.
  • Bias : Identifying research gaps can be influenced by researchers’ personal biases or perspectives, which can lead to a skewed understanding of the field.
  • Potential for disagreement: Identifying research gaps can be subjective, and different researchers may have different views on what constitutes a gap in the field, leading to disagreements and debate.

How To Find A Research Gap, Quickly

A step-by-step guide for new researchers

By: Derek Jansen (MBA) | Reviewer: Eunice Rautenbach (DTech) | April 2023

If you’ve got a dissertation, thesis or research project coming up, one of the first (and most important) things you’ll need to do is find a suitable research gap . In this post, we’ll share a straightforward process to help you uncover high-quality, original research gaps in a very time-efficient manner.

Overview: Finding Research Gaps

  • What exactly is a research gap?
  • Research gap vs research topic
  • How to find potential research gaps
  • How to evaluate research gaps (and topics)
  • Key takeaways

What is a research gap?

As a starting point, it’s useful to first define what we mean by research gap, to ensure we’re all on the same page. The term “research gap” gets thrown around quite loosely by students and academics alike, so let’s clear that up.

Simply put, a research gap is any space where there’s a lack of solid, agreed-upon research regarding a specific topic, issue or phenomenon. In other words, there’s a lack of established knowledge and, consequently, a need for further research.

Let’s look at a hypothetical example to illustrate a research gap.

Within the existing research regarding factors affect job satisfaction , there may be a wealth of established and agreed-upon empirical work within a US and UK context , but very little research within Eastern nations such as Japan or Korea . Given that these nations have distinctly different national cultures and workforce compositions compared to the West, it’s plausible that the factors that contribute toward job satisfaction may also be different. Therefore, a research gap emerges for studies that explore this matter.

This example is purely hypothetical (and there’s probably plenty of research covering this already), but it illustrates the core point that a research gap reflects a lack of firmly established knowledge regarding a specific matter . Given this lack, an opportunity exists for researchers (like you) to go on and fill the gap.

So, it’s the same as a research topic?

Not quite – but they are connected. A research gap refers to an area where there’s a lack of settled research , whereas a research topic outlines the focus of a specific study . Despite being different things, these two are related because research gaps are the birthplace of research topics. In other words, by identifying a clear research gap, you have a foundation from which you can build a research topic for your specific study. Your study is unlikely to resolve the entire research gap on it’s own, but it will contribute towards it .

If you’d like to learn more, we’ve got a comprehensive post that covers research gaps (including the different types of research gaps), as well as an explainer video below.

How to find a research gap

Now that we’ve defined what a research gap is, it’s time to get down to the process of finding potential research gaps that you can use as a basis for potential research topics. Importantly, it’s worth noting that this is just one way (of many) to find a research gap (and consequently a topic). We’re not proposing that it’s the only way or best way, but it’s certainly a relatively quick way to identify opportunities.

Step 1: Identify your broad area of interest

The very first step to finding a research gap is to decide on your general area of interest . For example, if you were undertaking a dissertation as part of an MBA degree, you may decide that you’re interested in corporate reputation, HR strategy, or leadership styles. As you can see, these are broad categories – there’s no need to get super specific just yet. Of course, if there is something very specific that you’re interested in, that’s great – but don’t feel pressured to narrow it down too much right now.

Equally important is to make sure that this area of interest is allowed by your university or whichever institution you’ll be proposing your research to. This might sound dead obvious, but you’ll be surprised how many times we’ve seen students run down a path with great excitement, only to later learn that their university wants a very specific area of focus in terms of topic (and their area of interest doesn’t qualify).

Step 2: Do an initial literature scan

Once you’ve pinned down your broad area (or areas) of interest, the next step is to head over to Google Scholar to undertake an initial literature scan . If you’re not familiar with this tool, Google Scholar is a great starting point for finding academic literature on pretty much any topic, as it uses Google’s powerful search capabilities to hunt down relevant academic literature. It’s certainly not the be-all and end-all of literature search tools, but it’s a useful starting point .

Within Google Scholar, you’ll want to do a few searches using keywords that are relevant to your area of interest. Sticking with our earlier example, we could use the key phrase “job satisfaction”, or we may want to get a little more specific – perhaps “job satisfaction for millennials” or “job satisfaction in Japan”.

It’s always a good idea to play around with as many keywords/phrases as you can think up.  Take an iterative approach here and see which keywords yield the most relevant results for you. Keep each search open in a new tab, as this will help keep things organised for the next steps.

Once you’ve searched for a few different keywords/phrases, you’ll need to do some refining for each of the searches you undertook. Specifically, you’ll need to filter the results down to the most recent papers . You can do this by selecting the time period in the top left corner (see the example below).

using google scholar to find a research gap

Filtering to the current year is typically a good choice (especially for fast-moving research areas), but in some cases, you may need to filter to the last two years . If you’re undertaking this task in January or February, for example, you’ll likely need to select a two-year period.

Step 3: Review and shortlist articles that interest you

Once you’ve run a few searches using different keywords and phrases, you’ll need to scan through the results to see what looks most relevant and interesting to you. At this stage, you can just look at the titles and abstracts (the description provided by Google Scholar) – don’t worry about reading the actual article just yet.

Next, select 5 – 10 articles that interest you and open them up. Here, we’re making the assumption that your university has provided you with access to a decent range of academic databases. In some cases, Google Scholar will link you directly to a PDF of the article, but in most cases, you’ll need paid access. If you don’t have this (for example, if you’re still applying to a university), you can look at two options:

Open-access articles – these are free articles which you can access without any journal subscription. A quick Google search (the regular Google) will help you find open-access journals in your area of interest, but you can also have a look at DOAJ and Elsevier Open Access.

DeepDyve – this is a monthly subscription service that allows you to get access to a broad range of journals. At the time of shooting this video, their monthly subscription is around $50 and they do offer a free trial, which may be sufficient for your project.

Step 4: Skim-read your article shortlist

Now, it’s time to dig into your article shortlist and do some reading. But don’t worry, you don’t need to read the articles from start to finish – you just need to focus on a few key sections.

Specifically, you’ll need to pay attention to the following:

  • The abstract (which you’ve probably already read a portion of in Google Scholar)
  • The introduction – this will give you a bit more detail about the context and background of the study, as well as what the researchers were trying to achieve (their research aims)
  • The discussion or conclusion – this will tell you what the researchers found

By skimming through these three sections for each journal article on your shortlist, you’ll gain a reasonable idea of what each study was about, without having to dig into the painful details. Generally, these sections are usually quite short, so it shouldn’t take you too long.

Step 5: Go “FRIN hunting”

This is where the magic happens. Within each of the articles on your shortlist, you’ll want to search for a few very specific phrases , namely:

  • Future research
  • Further research
  • Research opportunities
  • Research directions

All of these terms are commonly found in what we call the “FRIN” section . FRIN stands for “further research is needed”. The FRIN is where the researchers explain what other researchers could do to build on their study, or just on the research area in general. In other words, the FRIN section is where you can find fresh opportunities for novel research . Most empirical studies will either have a dedicated FRIN section or paragraph, or they’ll allude to the FRIN toward the very end of the article. You’ll need to do a little scanning, but it’s usually pretty easy to spot.

It’s worth mentioning that naturally, the FRIN doesn’t hand you a list of research gaps on a platter. It’s not a silver bullet for finding research gaps – but it’s the closest thing to it. Realistically, the FRIN section helps you shortcut the gap-hunting process  by highlighting novel research avenues that are worth exploring.

This probably sounds a little conceptual, so let’s have a look at a few examples:

The impact of overeducation on job outcomes: Evidence from Saudi Arabia (Alzubaidi, 2020)

If you scroll down to the bottom of this article, you’ll see there’s a dedicated section called “Limitations and directions for future research”. Here they talk about the limitations of the study and provide suggestions about how future researchers could improve upon their work and overcome the limitations.

Perceived organizational support and job satisfaction: a moderated mediation model of proactive personality and psychological empowerment (Maan et al, 2020)

In this article, within the limitations section, they provide a wonderfully systematic structure where they discuss each limitation, followed by a proposal as to how future studies can overcome the respective limitation. In doing so, they are providing very specific research opportunities for other researchers.

Medical professionals’ job satisfaction and telemedicine readiness during the COVID-19 pandemic: solutions to improve medical practice in Egypt (El-Mazahy et al, 2023)

In this article, they don’t have a dedicated section discussing the FRIN, but we can deduct it based on the limitations section. For example, they state that an evaluation of the knowledge about telemedicine and technology-related skills would have enabled studying their independent effect on the perception of telemedicine.

Follow this FRIN-seeking process for the articles you shortlisted and map out any potentially interesting research gaps . You may find that you need to look at a larger number of articles to find something interesting, or you might find that your area of interest shifts as you engage in the reading – this is perfectly natural. Take as much time as you need to develop a shortlist of potential research gaps that interest you.

Importantly, once you’ve developed a shortlist of potential research gaps, you need to return to Google Scholar to double-check that there aren’t fresh studies that have already addressed the gap. Remember, if you’re looking at papers from two years ago in a fast-moving field, someone else may have jumped on it . Nevertheless, there could still very well be a unique angle you could take – perhaps a contextual gap (e.g. a specific country, industry, etc.).

Ultimately, the need for originality will depend on your specific university’s requirements and the level of study. For example, if you’re doing an undergraduate research project, the originality requirements likely won’t be as gruelling as say a Masters or PhD project. So, make sure you have a clear understanding of what your university’s expectations are. A good way to do this is to look at past dissertations and theses for your specific programme. You can usually find these in the university library or by asking the faculty.

How to evaluate potential research gaps

Once you’ve developed a shortlist of potential research gaps (and resultant potential research topics) that interest you, you’ll need to systematically evaluate  them  to choose a winner. There are many factors to consider here, but some important ones include the following:

  • Originality and value – is the topic sufficiently novel and will addressing it create value?
  • Data access – will you be able to get access to the sample of interest?
  • Costs – will there be additional costs involved for data collection and/or analysis?
  • Timeframes – will you be able to collect and analyse the data within the timeframe required by your university?
  • Supervisor support – is there a suitable supervisor available to support your project from start to finish?

To help you evaluate your options systematically, we’ve got a topic evaluation worksheet that allows you to score each potential topic against a comprehensive set of criteria. You can access the worksheet completely free of charge here .

Recap: Key Takeaways

We’ve covered quite a lot of ground in this post. Here are the key takeaways:

  • A research gap is any space where there’s a lack of solid, agreed-upon research regarding a specific topic/issue/phenomenon.
  • Unique research topics emerge from research gaps , so it’s essential to first identify high-quality research gaps before you attempt to define a topic.
  • To find potential research gaps, start by seeking out recent journal articles on Google Scholar and pay particular attention to the FRIN section to identify novel opportunities.
  • Once you have a shortlist of prospective research gaps and resultant topic ideas, evaluate them systematically using a comprehensive set of criteria.

Library Guide to Capstone Literature Reviews: Find a Research Gap

Find a research gap: tips to get started.

Finding a research gap is not an easy process and there is no one linear path. These tips and suggestions are just examples of possible ways to begin. 

In Ph.D. dissertations, students identify a gap in research. In other programs, students identify a gap in practice. The literature review for a gap in practice will show the context of the problem and the current state of the research. 

Research gap definition

A research gap exists when:

  • a question or problem has not been answered by existing studies/research in the field 
  • a concept or new idea has not been studied at all
  • all the existing literature on a topic is outdated 
  • a specific population/location/age group etc has not been studied 

A research gap should be:

  • grounded in the literature
  • amenable to scientific study
  • Litmus Test for a Doctoral-Level Research Problem (Word) This tool helps students determine if they have identified a doctoral level research problem.

Identify a research gap

To find a gap you must become very familiar with a particular field of study. This will involve a lot of research and reading, because a gap is defined by what does (and does not) surround it.

  • Search the research literature and dissertations (search all university dissertations, not just Walden!).
  • Understand your topic! Review background information in books and encyclopedias . 
  • Look for literature reviews, systematic reviews, and meta-analyses.
  • Take notes on concepts, themes, and subject terms . 
  • Look closely at each article's limitations, conclusions, and recommendations for future research. 
  • Organize, analyze, and repeat!

  • Quick Answer: How do I find dissertations on a topic?

Start with broad searches

Use the Library Search (formerly Thoreau)  to do a broad search with just one concept at a time . Broad searches give you an idea of the academic conversation surrounding your topic.

  • Try the terms you know (keywords) first.
  • Look at the Subject Terms (controlled language) to brainstorm terms. 
  • Subject terms help you understand what terms are most used, and what other terms to try.
  • No matter what your topic is, not every researcher will be using the same terms. Keep an eye open for additional ways to describe your topic.
  • Guide: Subject Terms & Index Searches: Index Overview

Keep a list of terms

  • Create a list of terms
  • Example list of terms

This list will be a record of what terms are: 

  • related to or represent your topic
  • synonyms or antonyms
  • more or less commonly used
  • keywords (natural language) or subject terms (controlled language)
  • Synonyms & antonyms (database search skills)
  • Turn keywords into subject terms

Term I started with:

culturally aware 

Subject terms I discovered:

cultural awareness (SU) 

cultural sensitivity (SU) 

cultural competence (SU) 

Search with different combinations of terms

  • Combine search terms list
  • Combine search terms table
  • Video: Search by Themes

Since a research gap is defined by the absence of research on a topic, you will search for articles on everything that relates to your topic. 

  • List out all the themes related to your gap.
  • Search different combinations of the themes as you discover them (include search by theme video at bottom) 

For example, suppose your research gap is on the work-life balance of tenured and tenure-track women in engineering professions. In that case, you might try searching different combinations of concepts, such as: 

  • women and STEM 
  • STEM or science or technology or engineering or mathematics
  • female engineering professors 
  • tenure-track women in STEM
  • work-life balance and women in STEM
  • work-life balance and women professors
  • work-life balance and tenure

  • Walden University Award Winning Dissertations
  • Gossage, Lily Giang-Tien, "Work-Life Balance of Tenured and Tenure-Track Women Engineering Professors" (2019). Walden Dissertations and Doctoral Studies. 6435.

Break your topic into themes and try combining the terms from different themes in different ways. For example: 

Theme 1 and Theme 4

Theme 2 and Theme 1

Theme 3 and Theme 4

Track where more research is needed

Most research articles will identify where more research is needed. To identify research trends, use the literature review matrix to track where further research is needed. 

  • Download or create your own Literature Review Matrix (examples in links below).
  • Do some general database searches on broad topics.
  • Find an article that looks interesting.
  • When you read the article, pay attention to the conclusions and limitations sections.
  • Use the Literature Review Matrix to track where  'more research is needed' or 'further research needed'. NOTE:  you might need to add a column to the template.
  • As you fill in the matrix you should see trends where more research is needed.

There is no consistent section in research articles where the authors identify where more research is needed. Pay attention to these sections: 

  • limitations
  • conclusions
  • recommendations for future research

Published on January 2, 2023 by Shona McCombes . Revised on September 11, 2023.

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.

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.

how does literature review support to find out research gap

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 .

Framing challenges

  • Gap analysis for literature reviews and advancing useful knowledge

By Steve Wallis and Bernadette Wright 02/06/2020

The basics of research are seemingly clear. Read a lot of articles, see what’s missing, and conduct research to fill the gap in the literature. Wait a minute. What is that? ‘See what’s missing?’ How can we see something that is not there?

Imagine you are videoconferencing a colleague who is showing you the results of their project. Suddenly, the screen and sound cut out for a minute. After pressing some keys, you manage to restore the link; only to have your colleague ask, ‘What do you think?’. Of course, you know that you missed something from the presentation because of the disconnection. You can see that something is missing, and you know what to ask for to get your desired results, ‘Sorry, could you repeat that last minute of your presentation, please’. It’s not so easy when we’re looking at research results, proposals, or literature reviews.

While all research is, to some extent, useful, we’ve seen a lot of research that does not have the expected impact. That means wasted time, wasted money, under-served clients, and frustration on multiple levels. A big part of that problem is that directions for research are often chosen intuitively; in a sort of ad-hoc process. While we deeply respect the intuition of experts, that kind of process is not very rigorous.

In this post, we will show you how to ‘see the invisible’: How to identify the missing pieces in any study, literature review, or program analysis. With these straight-forward techniques, you will be able to better target your research in a more cost-effective way to fill those knowledge gaps to develop more effective theories, plans, and evaluations.

The first step is to choose your source material. That can be one or more articles, reports, or other study results. Of course, you want to be sure that the material you use is of high quality . Next, you want to create a causal map of your source material.

We’re going to go a bit abstract on you here because people sometimes get lost in the ‘content’ when what we are looking at here is more about the ‘structure’. Think of it like choosing how to buy a house based on how well it is built, rather than what color it is painted. So, instead of using actual concepts, we’ll refer to them as concepts A, B, C… and so on.

So, the text might say something like: ‘Our research shows that A causes B, B causes C, and D causes less C. Oh yes, and E is also important (although we’re not sure how it’s causally connected to A, B, C, or D)’.

When we draw causal maps from the source material we’ve found, we like to have key concepts in circles, with causal connections represented by arrows.

how does literature review support to find out research gap

Figure 1. Abstract example of a causal map of a theory

There are really three basic kinds of gaps for you to find: relevance/meaning, logic/structure, and data/evidence. Starting with structure, there is a gap any place where there are two circles NOT connected by a causal arrow. It is important to have at least two arrows pointing at each concept/circle for the same reason we like to have multiple independent variables for each dependent variable (although, with more complex maps, we’re learning to see these as interdependent variables).

For example, there is no arrow between A and D. Also, there is no arrow between E and any of the other concepts. Each of those is a structural gap – an opening for additional research.

You might also notice that there are two arrows pointing directly at C. Like having two independent variables and one dependent variable, it is structurally better to have at least two arrows pointing at each concept.

So, structurally , C is in good shape. This part of the map has the least need for additional research. A larger gap exists around B, because it has only one arrow pointing at it (the arrow from A to B). Larger still is the gap around A, D, and E; because they have no arrows pointing at them.

To get the greatest leverage for your research dollar, it is generally best to search for that second arrow. In short, one research question would be: What (aside from A) has a causal influence on B? Other good research questions would be (a) Is there a causal relationship between A and D? (b) Is there a causal relationship between E and any of the other concepts? (c) What else besides A helps cause B? (d) What are the causes of A, D, and E?

Now, let’s take a look at gaps in the data, evidence, or information upon which each causal arrow is established.

From structure to data

Here, we add to the drawing by making a note showing (very briefly) the kind of data supporting each causal arrow. We like to have that in a box – with a loopy line ‘typing’ the evidence to the connection. You can also use different colors to more easily differentiate between the concepts and the evidence on your map. You can also write the note along the length of the arrow.

Figure 2. Tying the data to the structure

From data to stakeholder relevance

Finally, the gap in meaning (relevance) asks if those studies were done with the ‘right’ people. By this, we mean people related to the situation or topic you are studying. Managers, line workers, clients, suppliers, those providing related services; all of those and more should be included. Similarly, you might look to a variety of academic disciplines, drawing expertise from psychology, sociology, business, economics, policy, and others.

Which participants or stakeholders are actually part of your research depends on the project. However, in general, having a broader selection of stakeholder groups results in a better map. This applies to both choosing what concepts go on the map and also who to contact for interviews and surveys.

Visualizing the gaps

All of these three gaps – gaps in structure, data, and stakeholder perspectives – can (and should) be addressed to help you choose more focused directions for your research – to generate research results that will have more impact. As a final note, remember that many gaps may be filled with secondary research; a new literature review that fills the gaps in the logic/structure, data/information, and meaning/relevance of your map so that your organisation can have a greater impact.

  • Restructuring evaluation findings into useful knowledge:

This approach helps you to avoid fuzzy understandings and the dangerous ‘pretence of knowledge’ that occasionally crops up in some reports and recommendations. Everyone can see that a piece is missing and so more easily agree where more research is needed to advance our knowledge to better serve our organisational and community constituents.

How to find and fill gaps in the literature [Research Gaps Made Easy]

As we dive deeper into the realm of research, one term repeatedly echoes in the corridors of academia: “gap in literature.”

But what does it mean to find a gap in the literature, and why is it so crucial for your research project?

A gap in the literature refers to an area that hasn’t been studied or lacks substantial inquiry in your field of study. Identifying such gaps allows you to contribute fresh insights and innovation, thereby extending the existing body of knowledge.

It’s the cornerstone for every dissertation or research paper, setting the stage for an introduction that explicitly outlines the scope and aim of your investigation.

This gap review isn’t limited to what has been published in peer-reviewed journals; it may also include conference papers, dissertations, or technical reports, i.e., types of papers that provide an overview of ongoing research. 

This step is where your detective work comes in—by spotting trends, common methodologies, and unanswered questions, you can unearth an opportunity to explore an unexplored domain, thereby finding a research gap. 

Why Looking for Research Gaps is Essential

Looking for research gaps is essential as it enables the discovery of novel and unique contributions to a particular field.

By identifying these gaps, found through methods such as analyzing concluding remarks of recent papers, literature reviews, examining research groups’ non-peer-reviewed outputs, and utilizing specific search terms on Google Scholar, one can discern the trajectory of ongoing research and unearth opportunities for original inquiry.

These gaps highlight areas of potential innovation, unexplored paths, and disputed concepts, serving as the catalyst for valuable contributions and progression in the field. Hence, finding research gaps forms the basis of substantial and impactful scientific exploration.

Then your research can contribute by finding and filling the gap in knowledge. 

Method 1: Utilizing Concluding Remarks of Recent Research

When embarking on a quest to find research gaps, the concluding remarks of recent research papers can serve as an unexpected treasure map.

This section of a paper often contains insightful comments on the limitations of the work and speculates on future research directions.

These comments, although not directly pointing to a research gap, can hint at where the research is heading and what areas require further exploration.

Consider these remarks as signposts, pointing you towards uncharted territories in your field of interest.

For example, you may come across a conclusion in a recent paper on artificial intelligence that indicates a need for more research on ethical considerations. This gives you a direction to explore – the ethical implications of AI. 

However, it’s important to bear in mind that while these statements provide valuable leads, they aren’t definitive indicators of research gaps. They provide a starting point, a clue to the vast research puzzle.

Your task is to take these hints, explore further, and discern the most promising areas for your investigation. It’s a bit like being a detective, except your clues come from scholarly papers instead of crime scenes!

Method 2: Examining Research Groups and Non-peer Reviewed Outputs

If concluding remarks are signposts to potential research gaps, non-peer reviewed outputs such as preprints, conference presentations, and dissertations are detailed maps guiding you towards the frontier of research.

These resources reflect the real-time development in the field, giving you a sense of the “buzz” that surrounds hot topics.

These materials, presented but not formally published, offer a sneak peek into ongoing studies, providing you with a rich source of information to identify emerging trends and potential research gaps.

For instance, a presentation on the impact of climate change on mental health might reveal a new line of research that’s in its early stages.

One word of caution: while these resources can be enlightening, they have not undergone the rigorous peer review process that published articles have.

This means the quality of research may vary and the findings should be interpreted with a critical eye. Remember, the key is to pinpoint where the research is heading and then carve out your niche within that sphere.

Exploring non-peer reviewed outputs allows you to stay ahead of the curve, harnessing the opportunity to investigate and contribute to a burgeoning area of study before it becomes mainstream.

Method 3: Searching for ‘Promising’ and ‘Preliminary’ Results on Google Scholar

With a plethora of research at your fingertips, Google Scholar can serve as a remarkable tool in your quest to discover research gaps. The magic lies in a simple trick: search for the phrases “promising results” or “preliminary results” within your research area. Why these specific phrases? Scientists often use them when they have encouraging but not yet fully verified findings.

To illustrate, consider an example. Type “promising results and solar cell” into Google Scholar, and filter by recent publications.

The search results will show you recent studies where researchers have achieved promising outcomes but may not have fully developed their ideas or resolved all challenges.

These “promising” or “preliminary” results often represent areas ripe for further exploration.

They hint at a research question that has been opened but not fully answered. However, tread carefully.

While these findings can indeed point to potential research gaps, they can also lead to dead ends. It’s crucial to examine these leads with a critical eye and further corroborate them with a comprehensive review of related research.

Nevertheless, this approach provides a simple, effective starting point for identifying research gaps, serving as a launchpad for your explorations.

Method 4: Reading Around the Subject

Comprehensive reading forms the bedrock of effective research. When hunting for research gaps, you need to move beyond just the preliminary findings and delve deeper into the context surrounding these results.

This involves broadening your view and reading extensively around your topic of interest.

In the course of your reading, you will start identifying common themes, reoccurring questions, and shared challenges in the research.

Over time, patterns will emerge, helping you recognize areas where research is thin or missing.

For instance, in studying autonomous vehicles, you might find recurring questions about regulatory frameworks, pointing to a potential gap in the legal aspects of this technology.

However, this method is not about scanning through a huge volume of literature aimlessly. It involves strategic and critical reading, looking for patterns, inconsistencies, and areas where the existing literature falls short.

It’s akin to painting a picture where some parts are vividly detailed while others remain sketchy. Your goal is to identify these sketchy areas and fill in the details.

So grab your academic reading list, and start diving into the ocean of knowledge. Remember, it’s not just about the depth, but also the breadth of your reading, that will lead you to a meaningful research gap.

Method 5: Consulting with Current Researchers

Few methods are as effective in uncovering research gaps as engaging in conversations with active researchers in your field of interest.

Current researchers, whether they are PhD students, postdoctoral researchers, or supervisors, are often deeply engaged in ongoing studies and understand the current challenges in their respective fields.

Start by expressing genuine interest in their work. Rather than directly asking for research gaps, inquire about the challenges they are currently facing in their projects.

You can ask, “What are the current challenges in your research?”

Their responses can highlight potential areas of exploration, setting you on the path to identifying meaningful research gaps.

Moreover, supervisors, particularly those overseeing PhD and Master’s students, often have ideas for potential research topics. By asking the right questions, you can tap into their wealth of knowledge and identify fruitful areas of study.

While the act of discovering research gaps can feel like a solitary journey, it doesn’t have to be.

Engaging with others who are grappling with similar challenges can provide valuable insights and guide your path. After all, the world of research thrives on collaboration and shared intellectual curiosity.

Method 6: Utilizing Online Tools

The digital age has made uncovering research gaps easier, thanks to a plethora of online tools that help visualize the interconnectedness of research literature.

Platforms such as:

  • Connected Papers,
  • ResearchRabbit, and

allow you to see how different papers in your field relate to one another, thereby creating a web of knowledge.

Upon creating this visual web, you may notice that many papers point towards a certain area, but then abruptly stop. This could indicate a potential research gap, suggesting that the topic hasn’t been adequately addressed or has been sidelined for some reason.

By further reading around this apparent gap, you can understand if it’s a genuine knowledge deficit or merely a research path that was abandoned due to inherent challenges or a dead end.

These online tools provide a bird’s eye view of the literature, helping you understand the broader landscape of research in your area of interest.

By examining patterns and relationships among studies, you can effectively zero in on unexplored areas, making these tools a valuable asset in your quest for research gaps.

Method 7: Seeking Conflicting Ideas in the Literature

In scientific research, areas of conflict can often be fertile ground for finding research gaps. These are areas where there’s a considerable amount of disagreement or ongoing debate among researchers.

If you can bring a fresh perspective, a new technique, or a novel hypothesis to such a contentious issue, you may well be on your way to uncovering a significant research gap.

Take, for instance, an area in psychology where there is a heated debate about the influence of nature versus nurture.

If you can introduce a new dimension to the debate or a method to test a novel hypothesis, you could potentially fill a significant gap in the literature.

Investigating areas of conflict not only opens avenues for exploring research gaps, but it also provides opportunities for you to make substantial contributions to your field. The key is to be able to see the potential for a new angle and to muster the courage to dive into contentious waters.

However, engaging with conflicts in research requires careful navigation.

Striking the right balance between acknowledging existing research and championing new ideas is crucial.

In the end, resolving these conflicts or adding significant depth to the debate can be incredibly rewarding and contribute greatly to your field.

The Right Perspective Towards Research Gaps

The traditional understanding of research gaps often involves seeking out a ‘bubble’ of missing knowledge in the sea of existing research, a niche yet to be explored. However, in today’s fast-paced research environment, these bubbles are becoming increasingly rare.

The paradigm of finding research gaps is shifting. It’s no longer just about seeking out holes in existing knowledge, but about understanding the leading edge of research and the directions it could take. It involves not just filling in the gaps but extending the boundaries of knowledge.

To identify such opportunities, develop a comprehensive understanding of the research landscape, identify emerging trends, and keep a close eye on recent advancements.

Look for the tendrils of knowledge extending out into the unknown and think about how you can push them further. It might be a challenging task, but it offers the potential for making substantial, impactful contributions to your field. 

Remember, every great innovation begins at the edge of what is known. That’s where your research gap might be hiding.

Wrapping up – Literature and research gaps

Finding and filling a gap in the literature is a task crucial to every research project. It begins with a systematic review of existing literature – a quest to identify what has been studied and more importantly, what hasn’t.

You must delve into the rich terrain of literature in their field, from the seminal, citation-heavy research articles to the fresh perspective of conference papers. Identifying the gap in the literature necessitates a thorough evaluation of existing studies to refine your area of interest and map the scope and aim of your future research.

The purpose is to explicitly identify the gap that exists, so you can contribute to the body of knowledge by providing fresh insights. The process involves a series of steps, from consulting with faculty and experts in the field to identify potential trends and outdated methodologies, to being methodological in your approach to identify gaps that have emerged.

Upon finding a gap in the literature, we’ll ideally have a clearer picture of the research need and an opportunity to explore this unexplored domain.

It is important to remember that the task does not end with identifying the gap. The real challenge lies in drafting a research proposal that’s objective, answerable, and can quantify the impact of filling this gap. 

It’s important to consult with your advisor, and also look at commonly used parameters and preliminary evidence. Only then can we complete the task of turning an identified gap in the literature into a valuable contribution to your field, a contribution that’s peer-reviewed and adds to the body of knowledge.

To find a research gap is to stand on the shoulders of giants, looking beyond the existing research to further expand our understanding of the world.

What is a ‘gap in the literature’?

The gap, also considered the missing piece or pieces in the research literature, is the area that has not yet been explored or is under-explored. This could be a population or sample (size, type, location, etc.), research method, data collection and/or analysis, or other research variables or conditions.

It is important to keep in mind, however, that just because you identify a gap in the research, it doesn't necessarily mean that your research question is worthy of exploration. You will want to make sure that your research will have valuable practical and/or theoretical implications. In other words, answering the research question could either improve existing practice and/or inform professional decision-making (Applied Degree), or it could revise, build upon, or create theoretical frameworks informing research design and practice (Ph.D Degree). See the Dissertation Center  for additional information about dissertation criteria at NU.

How do you identify the gaps?

Conducting an exhaustive literature review is your first step. As you search for journal articles, you will need to read critically across the breadth of the literature to identify these gaps. You goal should be to find a ‘space’ or opening for contributing new research. The first step is gathering a broad range of research articles on your topic. You may want to look for research that approaches the topic from a variety of methods – qualitative, quantitative, or mixed methods. 

See the videos below for further instruction on identifying a gap in the literature.

Literature Gap & Future Research - Library Workshop

This workshop presents effective search techniques for identifying a gap in the literature and recommendations for future research.

Where can you locate research gaps?

As you begin to gather the literature, you will want to critically read for what has, and has not, been learned from the research. Use the Discussion and Future Research sections of the articles to understand what the researchers have found and where they point out future or additional research areas. This is similar to identifying a gap in the literature, however, future research statements come from a single study rather than an exhaustive search. You will want to check the literature to see if those research questions have already been answered.

Roadrunner Search

Identifying the gap in the research relies on an exhaustive review of the literature. Remember, researchers may not explicitly state that a gap in the literature exists; you may need to thoroughly review and assess the research to make that determination yourself.

However, there are techniques that you can use when searching in NavigatorSearch to help identify gaps in the literature. You may use search terms such as "literature gap " or "future research" "along with your subject keywords to pinpoint articles that include these types of statements.

An example of the how to use the "Find Research Gaps in Minutes" guide as part of a literature review.

Marina Kisley avatar

Finding research gaps is vital, both for identifying potential areas of research and to have an accurate understanding of the research landscape. A great way to find research gaps is by searching across references in a literature review.

This is useful in several contexts. While creating your own literature review, it ensures you don't miss any relevant papers. Additionally, it can be beneficial when analyzing an existing literature review, to ensure it comprehensively covers the given topic. Lastly, this technique can be used to just find relevant papers, using the references from a literature review as a start.

Is this not what you were looking for?

Check out our Find Research Gaps in Minutes guide for the bigger picture.

1. Get references from literature review

You can easily save all the references for any article in Litmaps. You can do this for any article anywhere in the app, but the directions below focus on how to do it for a Seed Map.

Create a Seed Map for your paper ( here's how )

Click on your Seed article on the visualization

Click References

Select all references by hitting the Select All icon

Click the folder icon

Click "New Collection" at the top

Create and name a collection for the references for this paper

2. Use Discover to find missing papers

Next, we'll explore the library using the Discover tool.

Import the library from your reference manager by going to Litmaps Discover and using the Import Articles option.

Discover shows new papers in the outer ring. Since the library papers represent all those referenced in the literature review, those in the outer ring can be considered “missing” from the literature review. In this case, we are interested in papers published before the date of this paper's publication (2007). These represent relevant and highly cited papers that the original literature review did not review.

In this Shilajit example, Discover identified three papers published before 2007! One of these is a highly ranked 2002 review paper that we'd expect the 2007 paper to reference. However, the 2002 paper referred to Shilajit using another name, " Mumie". This may explain why the 2007 paper authors didn't discover and reference it at the time.

3. Use other search algorithms

By default, Litmaps uses "Top Connected" as the search algorithm, to find the most relevant papers based on the citation network. You can also search using other algorithms. Here's a breakdown:

Top Connected: Find relevant, connected papers based on the citation network. Useful for: discovering impactful papers in your topic.

Co-Author Search: Find the most relevant works based on what papers authors in you original collections have worked together on. Useful for: finding key authors and their papers.

Semantic Search: Find relevant papers based on content similarity. Useful for: finding less-cited work and spotting new connections.

Plus, Litmaps Pro subscribers can also use

Keyword filter: Keywords are automatically detected from your articles, and useful in finding papers on specific sub-topics.

Data filter: See articles published in certain date ranges. This is especially useful if you’re searching for new advances in research since a given paper was published.

4. Add missing papers to your library

Add new papers to your library simply by hitting the "plus" next to an article's title. When you click Finish to end the search, you'll be able to export these articles for your reference manager, or save them to a collection.

Writing an effective literature review

Lorelei lingard.

Schulich School of Medicine & Dentistry, Health Sciences Addition, Western University, London, Ontario Canada

In the Writer’s Craft section we offer simple tips to improve your writing in one of three areas: Energy, Clarity and Persuasiveness. Each entry focuses on a key writing feature or strategy, illustrates how it commonly goes wrong, teaches the grammatical underpinnings necessary to understand it and offers suggestions to wield it effectively. We encourage readers to share comments on or suggestions for this section on Twitter, using the hashtag: #how’syourwriting?

This Writer’s Craft instalment is the first in a two-part series that offers strategies for effectively presenting the literature review section of a research manuscript. This piece alerts writers to the importance of not only summarizing what is known but also identifying precisely what is not, in order to explicitly signal the relevance of their research. In this instalment, I will introduce readers to the mapping the gap metaphor, the knowledge claims heuristic, and the need to characterize the gap.

Mapping the gap

The purpose of the literature review section of a manuscript is not to report what is known about your topic. The purpose is to identify what remains unknown— what academic writing scholar Janet Giltrow has called the ‘knowledge deficit’ — thus establishing the need for your research study [ 1 ]. In an earlier Writer’s Craft instalment, the Problem-Gap-Hook heuristic was introduced as a way of opening your paper with a clear statement of the problem that your work grapples with, the gap in our current knowledge about that problem, and the reason the gap matters [ 2 ]. This article explains how to use the literature review section of your paper to build and characterize the Gap claim in your Problem-Gap-Hook. The metaphor of ‘mapping the gap’ is a way of thinking about how to select and arrange your review of the existing literature so that readers can recognize why your research needed to be done, and why its results constitute a meaningful advance on what was already known about the topic.

Many writers have learned that the literature review should describe what is known. The trouble with this approach is that it can produce a laundry list of facts-in-the-world that does not persuade the reader that the current study is a necessary next step. Instead, think of your literature review as painting in a map of your research domain: as you review existing knowledge, you are painting in sections of the map, but your goal is not to end with the whole map fully painted. That would mean there is nothing more we need to know about the topic, and that leaves no room for your research. What you want to end up with is a map in which painted sections surround and emphasize a white space, a gap in what is known that matters. Conceptualizing your literature review this way helps to ensure that it achieves its dual goal: of presenting what is known and pointing out what is not—the latter of these goals is necessary for your literature review to establish the necessity and importance of the research you are about to describe in the methods section which will immediately follow the literature review.

To a novice researcher or graduate student, this may seem counterintuitive. Hopefully you have invested significant time in reading the existing literature, and you are understandably keen to demonstrate that you’ve read everything ever published about your topic! Be careful, though, not to use the literature review section to regurgitate all of your reading in manuscript form. For one thing, it creates a laundry list of facts that makes for horrible reading. But there are three other reasons for avoiding this approach. First, you don’t have the space. In published medical education research papers, the literature review is quite short, ranging from a few paragraphs to a few pages, so you can’t summarize everything you’ve read. Second, you’re preaching to the converted. If you approach your paper as a contribution to an ongoing scholarly conversation,[ 2 ] then your literature review should summarize just the aspects of that conversation that are required to situate your conversational turn as informed and relevant. Third, the key to relevance is to point to a gap in what is known. To do so, you summarize what is known for the express purpose of identifying what is not known . Seen this way, the literature review should exert a gravitational pull on the reader, leading them inexorably to the white space on the map of knowledge you’ve painted for them. That white space is the space that your research fills.

Knowledge claims

To help writers move beyond the laundry list, the notion of ‘knowledge claims’ can be useful. A knowledge claim is a way of presenting the growing understanding of the community of researchers who have been exploring your topic. These are not disembodied facts, but rather incremental insights that some in the field may agree with and some may not, depending on their different methodological and disciplinary approaches to the topic. Treating the literature review as a story of the knowledge claims being made by researchers in the field can help writers with one of the most sophisticated aspects of a literature review—locating the knowledge being reviewed. Where does it come from? What is debated? How do different methodologies influence the knowledge being accumulated? And so on.

Consider this example of the knowledge claims (KC), Gap and Hook for the literature review section of a research paper on distributed healthcare teamwork:

KC: We know that poor team communication can cause errors. KC: And we know that team training can be effective in improving team communication. KC: This knowledge has prompted a push to incorporate teamwork training principles into health professions education curricula. KC: However, most of what we know about team training research has come from research with co-located teams—i. e., teams whose members work together in time and space. Gap: Little is known about how teamwork training principles would apply in distributed teams, whose members work asynchronously and are spread across different locations. Hook: Given that much healthcare teamwork is distributed rather than co-located, our curricula will be severely lacking until we create refined teamwork training principles that reflect distributed as well as co-located work contexts.

The ‘We know that …’ structure illustrated in this example is a template for helping you draft and organize. In your final version, your knowledge claims will be expressed with more sophistication. For instance, ‘We know that poor team communication can cause errors’ will become something like ‘Over a decade of patient safety research has demonstrated that poor team communication is the dominant cause of medical errors.’ This simple template of knowledge claims, though, provides an outline for the paragraphs in your literature review, each of which will provide detailed evidence to illustrate a knowledge claim. Using this approach, the order of the paragraphs in the literature review is strategic and persuasive, leading the reader to the gap claim that positions the relevance of the current study. To expand your vocabulary for creating such knowledge claims, linking them logically and positioning yourself amid them, I highly recommend Graff and Birkenstein’s little handbook of ‘templates’ [ 3 ].

As you organize your knowledge claims, you will also want to consider whether you are trying to map the gap in a well-studied field, or a relatively understudied one. The rhetorical challenge is different in each case. In a well-studied field, like professionalism in medical education, you must make a strong, explicit case for the existence of a gap. Readers may come to your paper tired of hearing about this topic and tempted to think we can’t possibly need more knowledge about it. Listing the knowledge claims can help you organize them most effectively and determine which pieces of knowledge may be unnecessary to map the white space your research attempts to fill. This does not mean that you leave out relevant information: your literature review must still be accurate. But, since you will not be able to include everything, selecting carefully among the possible knowledge claims is essential to producing a coherent, well-argued literature review.

Characterizing the gap

Once you’ve identified the gap, your literature review must characterize it. What kind of gap have you found? There are many ways to characterize a gap, but some of the more common include:

  • a pure knowledge deficit—‘no one has looked at the relationship between longitudinal integrated clerkships and medical student abuse’
  • a shortcoming in the scholarship, often due to philosophical or methodological tendencies and oversights—‘scholars have interpreted x from a cognitivist perspective, but ignored the humanist perspective’ or ‘to date, we have surveyed the frequency of medical errors committed by residents, but we have not explored their subjective experience of such errors’
  • a controversy—‘scholars disagree on the definition of professionalism in medicine …’
  • a pervasive and unproven assumption—‘the theme of technological heroism—technology will solve what ails teamwork—is ubiquitous in the literature, but what is that belief based on?’

To characterize the kind of gap, you need to know the literature thoroughly. That means more than understanding each paper individually; you also need to be placing each paper in relation to others. This may require changing your note-taking technique while you’re reading; take notes on what each paper contributes to knowledge, but also on how it relates to other papers you’ve read, and what it suggests about the kind of gap that is emerging.

In summary, think of your literature review as mapping the gap rather than simply summarizing the known. And pay attention to characterizing the kind of gap you’ve mapped. This strategy can help to make your literature review into a compelling argument rather than a list of facts. It can remind you of the danger of describing so fully what is known that the reader is left with the sense that there is no pressing need to know more. And it can help you to establish a coherence between the kind of gap you’ve identified and the study methodology you will use to fill it.

Do you want to contribute original research and make an impact in your field? If so, it's important to look for research gaps, or areas of study that are either under-researched or currently unexplored. In this article, we'll explain in detail the best way to identify a research gap—by performing a comprehensive literature review—so you can dive deep into your research topic and analyze articles critically and effectively. For more tips and tricks on identifying potential research gaps and how to proceed when you find one, read on.

Researching Your Topic

Step 1 Start with a broad topic related to your field of interest.

  • If you start with a narrow topic, you may struggle to find a gap in research, since you’ll be focused on fewer avenues of study.
  • For instance, a broad topic for social sciences research might be "organizational development" or "human motivation." For urban planning, a broad topic might be "walkable cities" or "traffic management."

Step 2 Conduct preliminary research to explore your topic.

  • While you can't include sources like Wikipedia and news websites on your literature review, it's okay to read them to get an overview of your topic and recent developments in your field.
  • It’s okay to narrow your topic as you learn more about it. However, keep your options open until you’re sure you’ve found an area with gaps in research.
  • Let's say you were researching human motivation. You might use search terms like "motivating workers," "goal setting," and "improving worker productivity."

Step 3 Compile a wide range of articles about your topic.

  • Your research needs to be very thorough to ensure that you’re actually finding a gap. If you only read a handful of articles, you may be missing other existing research that answers your proposed research question.

Tip: Look for both quantitative and qualitative research, if applicable to your field. This will give you a broader overview of the current research.

Step 4 Talk to an adviser or mentor about the current research in your field.

  • Ask them questions like, “Which areas of research are hot right now?” “What kinds of changes are happening within the field?” “What possible avenues of research do you see?” or “Do you think this topic is a good fit for me?”

Analyzing the Literature

Step 1 Read each article at least twice to help you understand it.

  • If you decide an article is unhelpful, it’s okay to skip the second reading.

Tip: Conducting a literature review is often a very time-consuming task. However, it’s also an essential part of identifying a research gap. Additionally, you can use the notes you take during your literature review when it comes time to write your article, thesis, or dissertation.

Step 2 Check the introduction to learn why the research is important.

  • As an example, an author might identify their gap in research with a statement like: “This subject has not been previously studied,” or “This question remains unanswered.”

Step 3 Write notes and...

  • If you keep your notes in a separate document, make sure you label them with the title of the article and the author’s name. This way you won’t accidentally get your notes mixed up.

Step 4 Look for the answers to your questions about the literature.

  • Save any questions that you can’t answer because they may be a starting point for writing a research question.

Step 5 Map out the existing research using a table, Venn diagram, or mind map.

  • For instance, you might make a research gap table in a spreadsheet. Create 3 columns and label them “Author,” “Year,” and "Summary." For each article, list the authors, year of publication, and a bullet point summary of the article contents.
  • Similarly, you may make a Venn diagram to compare 1 or more articles. Look for overlapping themes and methods, as well as differences between the articles.

Using Current Research, Key Concepts, or Trends

Step 1 Check the “discussion” and “future research” sections for gaps.

  • Keep in mind that other researchers may have addressed the gaps identified in a particular article since that article was written. However, this can give you a starting point for finding a potential gap.

Step 2 Read meta-analyses, literature reviews, and systematic reviews to identify trends.

  • Don’t rely solely on these types of papers when conducting your research. However, they can make a great supplement.

Step 3 Review the key concepts listed on journal websites to find hot topics.

  • Some journals will even tell you how many articles are pertaining to that key concept. If you see a key concept that has fewer articles than the others, that might be a good avenue for further research because it’s been studied less.

Step 4 Review Google trends to find questions asked about your topic.

  • You can access Google trends here: https://trends.google.com/trends/?geo=US
  • For instance, if you look up "organizational development" on Google trends, you'll see that people are looking for information on management development, mission statements, and software framework.

Expert Q&A

  • Reading Wikipedia articles related to your topic of study may help you identify a gap in research, though you can’t use those articles as sources. Look for areas where more citations are needed, unanswered questions, or sections that are underdeveloped.

Table of Contents

If you are a young researcher, or even still finishing your studies, you’ll probably notice that your academic environment revolves around certain research topics, probably linked to your department or to the interest of your mentor and direct colleagues. For example, if your department is currently doing research in nanotechnology applied to medicine, it is only natural that you feel compelled to follow this line of research. Hopefully, it’s something you feel familiar with and interested in – although you might take your own twists and turns along your career.

Many scientists end up continuing their academic legacy during their professional careers, writing about their own practical experiences in the field and adapting classic methodologies to a present context. However, each and every researcher dreams about being a pioneer in a subject one day, by discovering a topic that hasn’t been approached before by any other scientist. This is a research gap.

Research gaps are particularly useful for the advance of science, in general. Finding a research gap and having the means to develop a complete and sustained study on it can be very rewarding for the scientist (or team of scientists), not to mention how its new findings can positively impact our whole society.

How to Find a Gap in Research

How many times have you felt that you have finally formulated THAT new and exciting question, only to find out later that it had been addressed before? Probably more times than you can count.

There are some steps you can take to help identify research gaps, since it is impossible to go through all the information and research available nowadays:

  • Select a topic or question that motivates you: Research can take a long time and surely a large amount of physical, intellectual and emotional effort, therefore choose a topic that can keep you motivated throughout the process.
  • Find keywords and related terms to your selected topic: Besides synthesizing the topic to its essential core, this will help you in the next step.
  • Use the identified keywords to search literature: From your findings in the above step, identify relevant publications and cited literature in those publications.
  • Look for topics or issues that are missing or not addressed within (or related to) your main topic.
  • Read systematic reviews: These documents plunge deeply into scholarly literature and identify trends and paradigm shifts in fields of study. Sometimes they reveal areas or topics that need more attention from researchers and scientists.

How to find a Gap in Research

Keeping track of all the new literature being published every day is an impossible mission. Remember that there is technology to make your daily tasks easier, and reviewing literature can be one of them. Some online databases offer up-to-date publication lists with quite effective search features:

  • Elsevier’s Scope
  • Google Scholar

Of course, these tools may be more or less effective depending on knowledge fields. There might be even better ones for your specific topic of research; you can learn about them from more experienced colleagues or mentors.

Find out how FINER research framework can help you formulate your research question.

Literature Gap

The expression “literature gap” is used with the same intention as “research gap.” When there is a gap in the research itself, there will also naturally be a gap in the literature. Nevertheless, it is important to stress out the importance of language or text formulations that can help identify a research/literature gap or, on the other hand, making clear that a research gap is being addressed.

When looking for research gaps across publications you may have noticed sentences like:

…has/have not been… (studied/reported/elucidated) …is required/needed… …the key question is/remains… …it is important to address…

These expressions often indicate gaps; issues or topics related to the main question that still hasn’t been subject to a scientific study. Therefore, it is important to take notice of them: who knows if one of these sentences is hiding your way to fame.
