Parenthetical citations: (Grady et al., 2019; Jerrentrup et al., 2018)

Narrative citations: Grady et al. (2019) and Jerrentrup et al. (2018)

If a journal article has a DOI, include the DOI in the reference.
If the journal article does not have a DOI and is from an academic research database, end the reference after the page range (for an explanation of why, see the database information page). The reference in this case is the same as for a print journal article.
Do not include database information in the reference unless the journal article comes from a database that publishes original, proprietary content, such as UpToDate (see an example on the database information page).
If the journal article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online journal that is not part of a database), include the URL of the article at the end of the reference.
If the journal article has an article number instead of a page range, include the article number instead of the page range (as shown in the Jerrentrup et al. example).

Parenthetical citations: (Rabinowitz, 2019; Sapolsky, 2017)

Narrative citations: Rabinowitz (2019) and Sapolsky (2017)

If the book includes a DOI, include the DOI in the reference after the publisher name.
Do not include the publisher location.
If the book does not have a DOI and comes from an academic research database, end the book reference after the publisher name. Do not include database information in the reference. The reference in this case is the same as for a print book.

Parenthetical citations: (Schaefer & Shapiro, 2019; Schulman, 2019)

Narrative citations: Schaefer and Shapiro (2019) and Schulman (2019)

If a magazine article has a DOI, include the DOI in the reference.
If the magazine article does not have a DOI and is from an academic research database, end the reference after the page range. Do not include database information in the reference. The reference in this case is the same as for a print magazine article.
If the magazine article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online magazine that is not part of a database), include the URL of the article at the end of the reference.
If the magazine article does not have volume, issue, and/or page numbers (e.g., because it is from an online magazine), omit the missing elements from the reference (as in the Schulman example).

Parenthetical citation: (Carey, 2019)

Narrative citation: Carey (2019)

If the newspaper article is from an academic research database, end the reference after the page range. Do not include database information in the reference. The reference in this case is the same as for a print newspaper article.
If the newspaper article has a URL that will resolve for readers (e.g., it is from an online newspaper), include the URL of the article at the end of the reference.
If the newspaper article does not have volume, issue, and/or page numbers (e.g., because it is from an online newspaper), omit the missing elements from the reference, as shown in the example.
If the article is from a news website (e.g., CNN, HuffPost)—one that does not have an associated daily or weekly newspaper—use the format for a webpage on a website instead.

Parenthetical citation: (Aron et al., 2019)

Narrative citation: Aron et al. (2019)

If the edited book chapter includes a DOI, include the chapter DOI in the reference after the publisher name.
If the edited book chapter does not have a DOI and comes from an academic research database, end the edited book chapter reference after the publisher name. Do not include database information in the reference. The reference in this case is the same as for a print edited book chapter.
Do not create references for chapters of authored books. Instead, write a reference for the whole book and cite the chapter in the text if desired (e.g., Kumar, 2017, Chapter 2).

Parenthetical citation: (Merriam-Webster, n.d.)

Narrative citation: Merriam-Webster (n.d.)

Because entries in Merriam-Webster’s Dictionary are updated over time and are not archived, include a retrieval date in the reference.
Merriam-Webster is both the author and the publisher, so the name appears in the author element only to avoid repetition.
To quote a dictionary definition, view the pages on quotations and how to quote works without page numbers for guidance. Additionally, here is an example: Culture refers to the “customary beliefs, social forms, and material traits of a racial, religious, or social group” (Merriam-Webster, n.d., Definition 1a).

Parenthetical citation: (National Cancer Institute, 2019)

Narrative citation: National Cancer Institute (2019)

The specific agency responsible for the report appears as the author. The names of parent agencies not present in the group author name appear in the source element as the publisher. This creates concise in-text citations and complete reference list entries.

Parenthetical citation: (Harvard University, 2019)

Narrative citation: Harvard University (2019)

Use the name of the account that uploaded the video as the author.
If the account did not actually create the work, explain this in the text if it is important for readers to know. However, if that would mean citing a source that appears unauthoritative, you might also look for the author’s YouTube channel, official website, or other social media to see whether the same video is available elsewhere.

Parenthetical citations: (APA Databases, 2019; Gates, 2019)

Narrative citations: APA Databases (2019) and Gates (2019)

Present the name of the individual or group author the same as you would for any other reference. Then provide the Twitter handle (beginning with the @ sign) in square brackets, followed by a period.
Provide the first 20 words of the tweet as the title. Count a URL, a hashtag, or an emoji as one word each, and include them in the reference if they fall within the first 20 words.
If the tweet includes an image, a video, a poll, or a thumbnail image with a link, indicate that in brackets after the title: [Image attached], [Video attached], [Thumbnail with link attached].
The same format used for Twitter is also used for Instagram.

Parenthetical citation: (News From Science, 2019)

Narrative citation: News From Science (2019)

Provide the first 20 words of the Facebook post as the title. Count a URL or other link, a hashtag, or an emoji as one word each, and include them in the reference if they fall within the first 20 words.
If a status update includes images, videos, thumbnail links to outside sources, or content from another Facebook post (such as when sharing a link), indicate that in square brackets.

Parenthetical citations: (Fagan, 2019; National Institute of Mental Health, 2018; Woodyatt, 2019; World Health Organization, 2018)

Narrative citations: Fagan (2019), National Institute of Mental Health (2018), Woodyatt (2019), and World Health Organization (2018)

Provide as specific a date as is available on the webpage. This might be a year only; a year and month; or a year, month, and day.
Italicize the title of a webpage.
When the author of the webpage and the publisher of the website are the same, omit the publisher name to avoid repetition (as in the World Health Organization example).
When contents of a page are meant to be updated over time but are not archived, include a retrieval date in the reference (as in the Fagan example).
Use the webpage on a website format for articles from news websites such as CNN and HuffPost (these sites do not have associated daily or weekly newspapers). Use the newspaper article category for articles from newspaper websites such as The New York Times or The Washington Post .
Create a reference to an open educational resources (OER) page only when the materials are available for download directly (i.e., the materials are on the page and/or can be downloaded as PDFs or other files). If you are directed to another website, create a reference to the specific webpage on that website where the materials can be retrieved. Use this format for material in any OER repository, such as OER Commons, OASIS, or MERLOT.
Do not create a reference or in-text citation for a whole website. To mention a website in general, and not any particular information on that site, provide the name of the website in the text and include the URL in parentheses. For example, you might mention that you used a website to create a survey.

The following supplemental example references are mention in the Publication Manual:

retracted journal or magazine article
edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM)
edition of the International Statistical Classification of Diseases and Related Health Problems (ICD)
religious work
annotated religious work

Archival document and collections are not presented in the APA Publication Manual, Seventh Edition . This content is available only on the APA Style website . This guidance has been expanded from the 6th edition.

Archival sources include letters, unpublished manuscripts, limited-circulation brochures and pamphlets, in-house institutional and corporate documents, clippings, and other documents, as well as such nontextual materials as photographs and apparatus, that are in the personal possession of an author, form part of an institutional collection, or are stored in an archive such as the Archives of the History of American Psychology at the University of Akron or the APA Archives. For any documents like these that are available on the open web or via a database (subscription or nonsubscription), follow the reference templates shown in Chapter 10 of the Publication Manual.

The general format for the reference for an archival work includes the author, date, title, and source. The reference examples shown on this page may be modified for collections requiring more or less specific information to locate materials, for different types of collections, or for additional descriptive information (e.g., a translation of a letter). Authors may choose to list correspondence from their own personal collections, but correspondence from other private collections should be listed only with the permission of the collector.

Keep in mind the following principles when creating references to archival documents and collections:

As with any reference, the purpose is to direct readers to the source, despite the fact that only a single copy of the document may be available and readers may have some difficulty actually seeing a copy.
Include as much information as is needed to help locate the item with reasonable ease within the repository. For items from collections with detailed finding aids, the name of the collection may be sufficient; for items from collections without finding aids, more information (e.g., call number, box number, file name or number) may be necessary to help locate the item.
If several letters are cited from the same collection, list the collection as a reference and provide specific identifying information (author, recipient, and date) for each letter in the in-text citations (see Example 3).
Use square brackets to indicate information that does not appear on the document.
Use “ca.” (circa) to indicate an estimated date (see Example 5).
Use italics for titles of archival documents and collections; if the work does not have a title, provide a description in square brackets without italics.
Separate elements of the source (e.g., the name of a repository, library, university or archive, and the location of the university or archive) with commas. End the source with a period.
If a publication of limited circulation is available in libraries, the reference may be formatted as usual for published material, without the archival source.
Note that private letters (vs. those in an archive or repository) are considered personal communications and cited in the text only.

1. Letter from a repository

Frank, L. K. (1935, February 4). [Letter to Robert M. Ogden]. Rockefeller Archive Center (GEB Series 1.3, Box 371, Folder 3877), Tarrytown, NY, United States.

Parenthetical citation: (Frank, 1935)
Narrative citation: Frank (1935)
Because the letter does not have a title, provide a description in square brackets.

2. Letter from a private collection

Zacharius, G. P. (1953, August 15). [Letter to William Rickel (W. Rickel, Trans.)]. Copy in possession of Hendrika Vande Kemp.

Parenthetical citation: (Zacharius, 1953)
Narrative citation: Zacharius (1953)
In this example, Hendrika Vande Kemp is either the author of the paper or the author of the paper has received permission from Hendrika Vande Kemp to cite a letter in Vande Kemp’s private collection in this way. Otherwise, cite a private letter as a personal communication .

3. Collection of letters from an archive

Allport, G. W. (1930–1967). Correspondence. Gordon W. Allport Papers (HUG 4118.10), Harvard University Archives, Cambridge, MA, United States.

Parenthetical citation: (Allport, 1930–1967)
Narrative citation: Allport (1930–1967)

To cite specific letters in the text, provide the author and range of years as shown in the reference list entry, plus details about who wrote the specific letter to whom and when the specific letter was written.

Parenthetical citation: (Allport, 1930–1967, G. Boring to Allport, December 26, 1937)
Narrative citation: Allport (1930–1967, Allport to G. Boring, March 1, 1939)
Use the parenthetical citation format to cite a letter that E. G. Boring wrote to Allport because Allport is the author in the reference. Use either the parenthetical or narrative citation format to cite letters that Allport wrote.

4. Unpublished papers, lectures from an archive or personal collection

Berliner, A. (1959). Notes for a lecture on reminiscences of Wundt and Leipzig. Anna Berliner Memoirs (Box M50), Archives of the History of American Psychology, University of Akron, Akron, OH, United States.

Parenthetical citation: (Allport, ca. 1937)
Narrative citation: Allport (ca. 1937)
Because the author is reasonably certain but not stated on the document, place the word “presumed” in parentheses after the name, followed by a period.
Because the date is reasonably certain but not stated on the document, the abbreviation “ca.” (which stands for “circa”) appears before the year in parentheses.

6. Archival source with group author

Subcommittee on Mental Hygiene Personnel in School Programs. (1949, November 5–6). Meeting of Subcommittee on Mental Hygiene Personnel in School Programs. David Shakow Papers (M1360), Archives of the History of American Psychology, University of Akron, Akron, OH, United States.

Read the full APA guidelines on citing ChatGPT

OpenAI. (2023). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat

Parenthetical citation: (OpenAI, 2023)
Narrative citation: OpenAI (2023)

Author: The author of the model is OpenAI.

Date: The date is the year of the version you used. Following the template in Section 10.10, you need to include only the year, not the exact date. The version number provides the specific date information a reader might need.

Title: The name of the model is “ChatGPT,” so that serves as the title and is italicized in your reference, as shown in the template. Although OpenAI labels unique iterations (i.e., ChatGPT-3, ChatGPT-4), they are using “ChatGPT” as the general name of the model, with updates identified with version numbers.

The version number is included after the title in parentheses. The format for the version number in ChatGPT references includes the date because that is how OpenAI is labeling the versions. Different large language models or software might use different version numbering; use the version number in the format the author or publisher provides, which may be a numbering system (e.g., Version 2.0) or other methods.

Bracketed text is used in references for additional descriptions when they are needed to help a reader understand what’s being cited. References for a number of common sources, such as journal articles and books, do not include bracketed descriptions, but things outside of the typical peer-reviewed system often do. In the case of a reference for ChatGPT, provide the descriptor “Large language model” in square brackets. OpenAI describes ChatGPT-4 as a “large multimodal model,” so that description may be provided instead if you are using ChatGPT-4. Later versions and software or models from other companies may need different descriptions, based on how the publishers describe the model. The goal of the bracketed text is to briefly describe the kind of model to your reader.

Source: When the publisher name and the author name are the same, do not repeat the publisher name in the source element of the reference, and move directly to the URL. This is the case for ChatGPT. The URL for ChatGPT is https://chat.openai.com/chat . For other models or products for which you may create a reference, use the URL that links as directly as possible to the source (i.e., the page where you can access the model, not the publisher’s homepage).

What to include and what to exclude

Works included in a reference list.

The reference list provides a reliable way for readers to identify and locate the works cited in a paper. APA Style papers generally include reference lists, not bibliographies.

In general, each work cited in the text must appear in the reference list, and each work in the reference list must be cited in the text. Check your work carefully before submitting your manuscript or course assignment to ensure no works cited in the text are missing from the reference list and vice versa, with only the following exceptions.

Works Excluded From a Reference List

There are a few kinds of works that are not included in a reference list. Usually a work is not included because readers cannot recover it or because the mention is so broad that readers do not need a reference list entry to understand the use.

Information on works included in a reference list is covered in Sections 2.12 and 8.4 of the APA Publication Manual, Seventh Edition

*This guidance has been expanded from the 6th edition.*

Personal communications such as emails, phone calls, or text messages are cited in the text only, not in the reference list, because readers cannot retrieve personal communications.
General mentions of whole websites, whole periodicals, and common software and apps in the text do not require in-text citations or reference list entries because the use is broad and the source is familiar.
The source of an epigraph does not usually appear in the reference list unless the work is a scholarly book or journal. For example, if you open the paper with an inspirational quotation by a famous person, the source of the quotation does not appear in the reference list because the quotation is meant to set the stage for the work, not substantiate a key point.
Quotations from research participants in a study you conducted can be presented and discussed in the text but do not need citations or reference list entries. Citations and reference list entries are not necessary because the quotations are part of your original research. They could also compromise participants’ confidentiality, which is an ethical violation.
References included in a meta-analysis, which are marked with an asterisk in the reference list, may be cited in the text (or not) at the author’s discretion. This exception is relevant only to authors who are conducting a meta-analysis.

DOIs and URLs

The DOI or URL is the final component of a reference list entry. Because so much scholarship is available and/or retrieved online, most reference list entries end with either a DOI or a URL.

A DOI is a unique alphanumeric string that identifies content and provides a persistent link to its location on the internet. DOIs can be found in database records and the reference lists of published works.
A URL specifies the location of digital information on the internet and can be found in the address bar of your internet browser. URLs in references should link directly to the cited work when possible.

Follow these guidelines for including DOIs and URLs in references:

Include a DOI for all works that have a DOI, regardless of whether you used the online version or the print version.
If a print work does not have a DOI, do not include any DOI or URL in the reference.
If an online work has both a DOI and a URL, include only the DOI.
For works without DOIs from websites (not including academic research databases), provide a URL in the reference (as long as the URL will work for readers).
For works without DOIs from most academic research databases , do not include a URL or database information in the reference because these works are widely available. The reference should be the same as the reference for a print version of the work.
For works from databases that publish original, proprietary material available only in that database (such as the UpToDate database) or for works of limited circulation in databases (such as monographs in the ERIC database), include the name of the database or archive and the URL of the work. If the URL requires a login or is session-specific (meaning it will not resolve for readers), provide the URL of the database or archive home page or login page instead of the URL for the work. See the page on including database information in references for more information.
If the URL is no longer working or no longer provides readers access to the content you intend to cite, follow the guidance for works with no source .
Other alphanumeric identifiers such as the International Standard Book Number (ISBN) and the International Standard Serial Number (ISSN) are not included in APA Style references.

Follow these guidelines to format DOIs and URLs:

Present both DOIs and URLs as hyperlinks (i.e., beginning with “http:” or “https:”).
Because a hyperlink leads readers directly to the content, it is not necessary to include the words “Retrieved from” or “Accessed from” before a DOI or URL.
It is acceptable to use either the default display settings for hyperlinks in your word-processing program (e.g., usually blue font, underlined) or plain text that is not underlined.
Leave links live if the work is to be published or read online.
Follow the current recommendations of the International DOI Foundation to format DOIs in the reference list, which as of this publication is as follows:

https://doi.org/ xxxxx

The string “https://doi.org/” is a way of presenting a DOI as a link, and “xxxxx” refers to the DOI number.
The preferred format of the DOI has changed over time. Although older works use previous formats (e.g., “http:/dx.doi.org/” or “doi:” or “DOI:” before the DOI number), in your reference list, standardize DOIs into the current preferred format for all entries. For example, use https://doi.org/10.1037/a0040251 in your reference even though that article, published in 2016, presented the number in an older format.
Copy and paste the DOI or URL from your web browser directly into your reference list to avoid transcription errors. Do not change the capitalization or punctuation of the DOI or URL. Do not add line breaks manually to the hyperlink; it is acceptable if your word-processing program automatically adds a break or moves the hyperlink to its own line.
Do not add a period after the DOI or URL because this may interfere with link functionality.

When a DOI or URL is long or complex, you may use shortDOIs or shortened URLs if desired.

Use the shortDOI service provided by the International DOI Foundation to create shortDOIs. A work can have only one DOI and only one shortDOI; the shortDOI service will either produce a new shortDOI for a work that has never had one or retrieve an existing shortDOI.
Some websites provide their own branded shortened URLs, and independent URL shortening services are available as well. Any shortened URL is acceptable in a reference as long as you check the link to ensure that it takes you to the correct location.

Table of Contents

Research Paper Citation

Research paper citation refers to the act of acknowledging and referencing a previously published work in a scholarly or academic paper . When citing sources, researchers provide information that allows readers to locate the original source, validate the claims or arguments made in the paper, and give credit to the original author(s) for their work.

The citation may include the author’s name, title of the publication, year of publication, publisher, and other relevant details that allow readers to trace the source of the information. Proper citation is a crucial component of academic writing, as it helps to ensure accuracy, credibility, and transparency in research.

Be sure to provide enough information so your readers can locate the source on their own. When possible provide author or creator, year of publication, title, and publishing and/or retrieval data. When citing a chart, graph or map it may be best to follow the citation style for the format in which the information is presented.

All captions for charts should follow the guidelines below for captions for figures.

Captions for Figures (Charts, Graphs, and Maps): Publication manual of the American Psychological Association 5.20-5.25

All captions should be labeled as Figure followed by a number. The caption should begin with a descriptive phrase and include a citation to the original source and copyright information at the end.

MLA Sample Paper

Mla sample paper #1.

If you’ve been wondering how to produce a research paper that is strong in both formatting and writing, you’ve come to the right place.

Check out our first sample paper below. It is a helpful and clearly labeled visual aid to refer to. Note that while these sample papers do not include MLA abstracts , you should check with your instructor to see if an abstract should be included.

Visual Sample Paper

The example research paper below is one that was written in college for a course on the Inklings. The Inklings were a group of writers in England before WWII, including C.S. Lewis and J.R.R. Tolkien.

The abbreviated MLA paper below (linked here without annotations) is about J.R.R. Tolkien’s Lord of the Rings and how the author used myth, story, and song to link all of his works together. Tolkien is famous for creating a fantasy universe called Middle-earth, which readers can’t truly understand until they read all of the books about Middle-earth ( The Silmarillian, The Hobbit, and The Lord of the Rings ).

Since we’re here to learn how to format an essay, we’ve pointed out some important things about the paper to help you write a correctly formatted essay.

For starters, the essay is in MLA format. That means it follows the style manual of the Modern Language Association, which tells you how to format the paper itself and every source you cite. You’ll also see notes like how long a paragraph should be, how to use commas properly, and how to correctly punctuate a title. Some of these guidelines are different from those in APA format , so be sure to confirm you are using the correct style in your paper.

Pay special attention to the MLA format works cited. We only used one type of source (books), but both citations are correct according to the 9th edition of MLA, published in 2021. When you’re writing your own paper, you need to make sure you always use the most recent edition of the style manual. You’ll also want to check with your instructor to see if you need to include an MLA annotated bibliography with your paper, which contains additional information summarizing and evaluating each source after the regular citation.

Whether you need MLA, APA citations , or Chicago style notes, look up the latest edition before turning in a paper.

MLA Sample Paper #2

See below for an example paper or click below to download it as a Word Document.

The MLA header should be one inch from the top and left margins. The heading and the entire paper should be double spaced.

Privatization of Prisons in Texas

The privatization of governmental services has increased dramatically in the past decade as local, state, and federal agencies have searched for ways to cut costs while still meeting their mandated responsibility to provide various public services. This privatizing trend has particularly affected the criminal justice system. Since the early 1990s, privatized correctional facilities have increased significantly, nationally and statewide. This policy has far-ranging consequences not only within the criminal justice system, but as an instructive example for government officials when considering the costs and benefits of privatization as a public policy option. By 2001, thirty states, the District of Columbia, and Puerto Rico had privately-operated correctional facilities (Austin and Coventry 4). This movement has incited considerable debate and controversy, mainly because prison privatization calls for giving the private sector direct control over the lives of a captive human population.

Surprisingly, there has been little objective and concrete analysis of the privatization of prisons in the United States. This is probably for two reasons: first, ideological arguments on the matter have pushed out substantive research, and second, because this trend has only recently accelerated in the U.S. and mainly on a state level. However, case studies and statistics at the state level are more accessible. With capacity for over 30,000 prisoners in 43 facilities, the state of Texas has privatized more of its prison system than any state in the nation (McDonald and Patten Jr. iv).

Yaffarabe 2

Public policy concerning the criminal justice system has become more daunting and important in the last decade. The problems in the system are twofold: an overcrowding prison population, mainly due to “three strikes” legislation and reducing early parole; and the costs of operating prisons with this growing population (Austin and Coventry). According to the most recent U.S. Department of Justice survey, slightly over 2.2 million people were incarcerated in correctional facilities in this country in 2003. In comparison, in 1993, 1.37 million people were imprisoned in this country (Beck and Harrison 1).

At the same time, the growth of privately operated correctional facilities has increased significantly in this country. Private prisons now hold 95,522 inmates in this country, which is 6.5 percent of total prisoners (Beck and Harrison 5). In Texas, 16,570 inmates (10 percent of its prison population) are held in private facilities, about 10,000 more than the next highest state. Furthermore, six states had at least 25 percent of their prison population housed in private prisons, led by New Mexico (44%), Alaska (31%), and Montana (29%). These current statistics show that while state governments have been forced to manage and operate overcrowded and over-capacity prisons at considerable costs, many have turned to the private sector to operate prisons (McDonald and Patten Jr.). According to the General Accounting Office, prison operating costs have grown steadily since 1980, increasing almost 550 percent since 1980 based on inflation-adjusted dollars (Austin and Coventry 1).

Prison privatization started in the early 1980s, ostensibly to ease the burden on taxpayers by offering financial relief to private companies to run state prisons. Thomas Beasley founded Corrections Corporation of America in 1983, “the nation’s leader in the construction and management of private prisons” (Darling). That year, Corrections Corporation of America set up the first privately-operated prison in Tennessee. Since then, the number of private

Yaffarabe 3

correctional facility firms has grown to 14 (Austin and Coventry 3). The privatization of prisons occurs in two ways. First, state government can contract out (or outsource) specific services in a correctional facility to a private company after a bidding process. Second, and more radically, private companies build their own privately-managed prisons and contract with state governments to house their inmates. This latter approach, giving private correctional facility firms wide latitude over inmates, is taken in the Texas criminal justice system. In fact, many of these privately operated facilities “have no relationship at all with the state governments in these states, other than an obligation to pay corporate income taxes” (McDonald and Patten Jr. v).

An in-text citation is a short citation that is placed next to the text being cited. The basic element needed for an in-text citation is the author’s name . The publication year is not required in in-text citations. Sometimes, page numbers or line numbers are also included, especially when text is quoted from the source being cited. In-text citations are mentioned in the text in two ways: as a citation in prose or a parenthetical citation.

Citations in prose are incorporated into the text and act as a part of the sentence. Usually, citations in prose use the author’s full name when cited the first time in the text. Thereafter, only the surname is used. Avoid including the middle initial even if it is present in the works-cited-list entry. An example of the first citation in prose for a source with one author is given below:

Doug Barry explains the status of the UK.

Parenthetical

Parenthetical citations add only the author’s surname at the end of the sentence in parentheses. An example of a parenthetical citation is given below:

The status of the UK is explained (Barry).

Examples of in-text citations

Here are a few examples of in-text citations for works with various numbers and types of authors:

Use both the first name and surname of the author if you are mentioning the author for the first time in the prose. In subsequent occurrences, use only the author’s surname. Always use only the author’s surname in parenthetical citations.

Citation in prose:

First mention: Stephen George asserts …. (17).

Subsequent occurrences: George argues …. (17).

Parenthetical:

…. (George 17).

Two authors

Use the first name and surname of both authors if you are mentioning the work for the first time in the prose. In subsequent occurrences, use only the surnames of the two authors. Always use only the authors’ surnames in parenthetical citations. Use “and” to separate the two authors in parenthetical citations.

First mention: Kane Williams and Clark Ronald ….

Subsequent occurrences: Williams and Ronald ….

…. (Williams and Ronald).

Three or more authors

For citations in prose, use the first name and surname of the first author followed by “and others” or “and colleagues.” For parenthetical citations, use only the surname of the first author followed by “et al.”

Krishnan Sethu and colleagues…. or Krishnan Sethu and others ….

…. (Sethu et al.).

Corporate author

For citations in prose, treat the corporate author like you would treat the author’s name. For parenthetical citations, shorten the organization name to the shortest noun phrase. For example, shorten the Modern Language Association of America to Modern Language Association.

The Language Literary Association of Canada….

…. (Language Literary Association).

If there is no author for the source, use the source’s title in place of the author’s name for both citations in prose and parenthetical citations.

When you add such in-text citations, italicize the text of the title. If the source title is longer than a noun phrase, use a shortened version of the title. For example, shorten the title Fantastic Beasts and Where to Find Them to Fantastic Beasts .

Endgame explains …. (121).

…. ( Endgame 121).

In MLA style, two types of citations are used to cite a source: a short citation used within the text (called the in-text citation) and a full citation (called the works cited list entry) within the works cited list, which appears at the end of a paper.

The works cited list entry provides the complete details of a source. An in-text citation is a short citation that is placed next to the text being cited. The in-text citation lets the reader know that the information is derived from the cited source, and helps the reader find the full citation within the works cited list.

In order to properly cite a source in MLA style, you must have both citation types in your paper. Every in-text citation has a works cited list entry. Every works cited list entry has at least one (maybe more) corresponding in-text citation.

In-text citations

The basic element needed for an in-text citation is the author’s surname . The publication year is not required in in-text citations. Sometimes, page numbers or line numbers are also included, especially when text is quoted from the source being cited.

First mention: Sian Anderson studies ….

Subsequent occurrences: Anderson analyzes ….

….(Anderson)

or if quoting directly:

…(Anderson 9)

First mention: Paul Fin and Anna Gabriel ….

Subsequent occurrences: Fin and Gabriel ….

….(Fin and Gabriel)

…(Fin and Gabriel 27)

Paul Hill and colleagues…. or Paul Hill and others ….

….(Hill et al.)

…(Hill et al. 138)

How to Write a Research Paper Introduction (with Examples)

The research paper introduction section, along with the Title and Abstract, can be considered the face of any research paper. The following article is intended to guide you in organizing and writing the research paper introduction for a quality academic article or dissertation.

The research paper introduction aims to present the topic to the reader. A study will only be accepted for publishing if you can ascertain that the available literature cannot answer your research question. So it is important to ensure that you have read important studies on that particular topic, especially those within the last five to ten years, and that they are properly referenced in this section. 1 What should be included in the research paper introduction is decided by what you want to tell readers about the reason behind the research and how you plan to fill the knowledge gap. The best research paper introduction provides a systemic review of existing work and demonstrates additional work that needs to be done. It needs to be brief, captivating, and well-referenced; a well-drafted research paper introduction will help the researcher win half the battle.

The introduction for a research paper is where you set up your topic and approach for the reader. It has several key goals:

Present your research topic
Capture reader interest
Summarize existing research
Position your own approach
Define your specific research problem and problem statement
Highlight the novelty and contributions of the study
Give an overview of the paper’s structure

The research paper introduction can vary in size and structure depending on whether your paper presents the results of original empirical research or is a review paper. Some research paper introduction examples are only half a page while others are a few pages long. In many cases, the introduction will be shorter than all of the other sections of your paper; its length depends on the size of your paper as a whole.

The introduction in a research paper is placed at the beginning to guide the reader from a broad subject area to the specific topic that your research addresses. They present the following information to the reader

Scope: The topic covered in the research paper
Context: Background of your topic
Importance: Why your research matters in that particular area of research and the industry problem that can be targeted

The research paper introduction conveys a lot of information and can be considered an essential roadmap for the rest of your paper. A good introduction for a research paper is important for the following reasons:

It stimulates your reader’s interest: A good introduction section can make your readers want to read your paper by capturing their interest. It informs the reader what they are going to learn and helps determine if the topic is of interest to them.
It helps the reader understand the research background: Without a clear introduction, your readers may feel confused and even struggle when reading your paper. A good research paper introduction will prepare them for the in-depth research to come. It provides you the opportunity to engage with the readers and demonstrate your knowledge and authority on the specific topic.
It explains why your research paper is worth reading: Your introduction can convey a lot of information to your readers. It introduces the topic, why the topic is important, and how you plan to proceed with your research.
It helps guide the reader through the rest of the paper: The research paper introduction gives the reader a sense of the nature of the information that will support your arguments and the general organization of the paragraphs that will follow. It offers an overview of what to expect when reading the main body of your paper.

What are the parts of introduction in the research?

A good research paper introduction section should comprise three main elements: 2

What is known: This sets the stage for your research. It informs the readers of what is known on the subject.
What is lacking: This is aimed at justifying the reason for carrying out your research. This could involve investigating a new concept or method or building upon previous research.
What you aim to do: This part briefly states the objectives of your research and its major contributions. Your detailed hypothesis will also form a part of this section.

How to write a research paper introduction?

The first step in writing the research paper introduction is to inform the reader what your topic is and why it’s interesting or important. This is generally accomplished with a strong opening statement. The second step involves establishing the kinds of research that have been done and ending with limitations or gaps in the research that you intend to address. Finally, the research paper introduction clarifies how your own research fits in and what problem it addresses. If your research involved testing hypotheses, these should be stated along with your research question. The hypothesis should be presented in the past tense since it will have been tested by the time you are writing the research paper introduction.

The following key points, with examples, can guide you when writing the research paper introduction section:

Highlight the importance of the research field or topic
Describe the background of the topic
Present an overview of current research on the topic

Example: The inclusion of experiential and competency-based learning has benefitted electronics engineering education. Industry partnerships provide an excellent alternative for students wanting to engage in solving real-world challenges. Industry-academia participation has grown in recent years due to the need for skilled engineers with practical training and specialized expertise. However, from the educational perspective, many activities are needed to incorporate sustainable development goals into the university curricula and consolidate learning innovation in universities.

Reveal a gap in existing research or oppose an existing assumption
Formulate the research question

Example: There have been plausible efforts to integrate educational activities in higher education electronics engineering programs. However, very few studies have considered using educational research methods for performance evaluation of competency-based higher engineering education, with a focus on technical and or transversal skills. To remedy the current need for evaluating competencies in STEM fields and providing sustainable development goals in engineering education, in this study, a comparison was drawn between study groups without and with industry partners.

State the purpose of your study
Highlight the key characteristics of your study
Describe important results
Highlight the novelty of the study.
Offer a brief overview of the structure of the paper.

Example: The study evaluates the main competency needed in the applied electronics course, which is a fundamental core subject for many electronics engineering undergraduate programs. We compared two groups, without and with an industrial partner, that offered real-world projects to solve during the semester. This comparison can help determine significant differences in both groups in terms of developing subject competency and achieving sustainable development goals.

The purpose of the research paper introduction is to introduce the reader to the problem definition, justify the need for the study, and describe the main theme of the study. The aim is to gain the reader’s attention by providing them with necessary background information and establishing the main purpose and direction of the research.

The length of the research paper introduction can vary across journals and disciplines. While there are no strict word limits for writing the research paper introduction, an ideal length would be one page, with a maximum of 400 words over 1-4 paragraphs. Generally, it is one of the shorter sections of the paper as the reader is assumed to have at least a reasonable knowledge about the topic. 2 For example, for a study evaluating the role of building design in ensuring fire safety, there is no need to discuss definitions and nature of fire in the introduction; you could start by commenting upon the existing practices for fire safety and how your study will add to the existing knowledge and practice.

When deciding what to include in the research paper introduction, the rest of the paper should also be considered. The aim is to introduce the reader smoothly to the topic and facilitate an easy read without much dependency on external sources. 3 Below is a list of elements you can include to prepare a research paper introduction outline and follow it when you are writing the research paper introduction. Topic introduction: This can include key definitions and a brief history of the topic. Research context and background: Offer the readers some general information and then narrow it down to specific aspects. Details of the research you conducted: A brief literature review can be included to support your arguments or line of thought. Rationale for the study: This establishes the relevance of your study and establishes its importance. Importance of your research: The main contributions are highlighted to help establish the novelty of your study Research hypothesis: Introduce your research question and propose an expected outcome. Organization of the paper: Include a short paragraph of 3-4 sentences that highlights your plan for the entire paper

Cite only works that are most relevant to your topic; as a general rule, you can include one to three. Note that readers want to see evidence of original thinking. So it is better to avoid using too many references as it does not leave much room for your personal standpoint to shine through. Citations in your research paper introduction support the key points, and the number of citations depend on the subject matter and the point discussed. If the research paper introduction is too long or overflowing with citations, it is better to cite a few review articles rather than the individual articles summarized in the review. A good point to remember when citing research papers in the introduction section is to include at least one-third of the references in the introduction.

The literature review plays a significant role in the research paper introduction section. A good literature review accomplishes the following: Introduces the topic – Establishes the study’s significance – Provides an overview of the relevant literature – Provides context for the study using literature – Identifies knowledge gaps However, remember to avoid making the following mistakes when writing a research paper introduction: Do not use studies from the literature review to aggressively support your research Avoid direct quoting Do not allow literature review to be the focus of this section. Instead, the literature review should only aid in setting a foundation for the manuscript.

Remember the following key points for writing a good research paper introduction: 4

Avoid stuffing too much general information: Avoid including what an average reader would know and include only that information related to the problem being addressed in the research paper introduction. For example, when describing a comparative study of non-traditional methods for mechanical design optimization, information related to the traditional methods and differences between traditional and non-traditional methods would not be relevant. In this case, the introduction for the research paper should begin with the state-of-the-art non-traditional methods and methods to evaluate the efficiency of newly developed algorithms.
Avoid packing too many references: Cite only the required works in your research paper introduction. The other works can be included in the discussion section to strengthen your findings.
Avoid extensive criticism of previous studies: Avoid being overly critical of earlier studies while setting the rationale for your study. A better place for this would be the Discussion section, where you can highlight the advantages of your method.
Avoid describing conclusions of the study: When writing a research paper introduction remember not to include the findings of your study. The aim is to let the readers know what question is being answered. The actual answer should only be given in the Results and Discussion section.

To summarize, the research paper introduction section should be brief yet informative. It should convince the reader the need to conduct the study and motivate him to read further.
