What is a Citation Style?

A citation style is a standardized format for citing sources in academic and research papers. It provides guidelines for how to properly reference books, articles, websites, and other materials to give credit to the original authors. 

It also enables readers to locate the sources easily. Common citation styles include APA, MLA, Chicago, and Harvard styles.

All citation styles contain the same information elements. They include the author's name, title of the work, publication year, page numbers, website name, and place of publication. However, the order and formatting of these elements vary between different citation styles.

Why is Following Citation Styles Important?

The main reason to cite the added sources and details is to avoid academic theft and intellectual dishonesty. Adding and presenting ideas and quotes of other scholars and researchers without crediting them properly is punishable by law. The person would even have to face legal consequences.

Components of a Research Paper Citation

Citing a research paper involves more than just acknowledging the source; it requires a systematic approach that includes various essential components. 

Let's dive into the 6 key elements of a research paper citation:

1. Title of the Paper

• The title represents the essence of the research paper. Accurate citation ensures that readers can quickly identify the source and the specific topic under consideration. Examples of Properly Formatted Paper Titles: In APA style: "The Impact of Climate Change on Global Biodiversity" In MLA style: "Exploring the Role of Artificial Intelligence in Healthcare"

2. Author(s) of the Paper

• Citing authors acknowledges their intellectual contribution and provides credibility to your research. It also allows readers to trace the original work for deeper exploration.

3. Journal or Source Information

Properly citing the journal or source where the paper was published helps readers verify the credibility of the source and locate it for further reading. When citing online sources, include the full URL or DOI for accessibility.

4. Publication Date

Publication dates indicate the currency of the source. In fields where information evolves rapidly, citing outdated sources can misinform readers.

5. Page Numbers

Page numbers are crucial when citing specific ideas, quotes, or data from a research paper. They allow readers to pinpoint the exact location of the information within the source.

6. DOI (Digital Object Identifier)

A DOI is a unique alphanumeric string assigned to a digital publication. It ensures a stable and permanent link to the source, making it easy for readers to access and verify the paper.

How to Cite a Research Paper in Different Referencing Styles?

Frequently Asked Questions

What are the rules for citing figures, tables, and images from research papers.

When citing these elements from research papers, use a caption beneath each, including a figure or table number, title, and source citation. In the text, refer to them by their respective numbers (e.g., "Figure 1" or "Table 2").

What is the consequence of not citing a research paper properly?

Improperly citing a research paper can lead to accusations of plagiarism, academic penalties, and damage to one's credibility. Proper citation is essential for giving credit to original authors and maintaining academic integrity.

What is the difference between a bibliography and a reference list?

A bibliography includes all sources consulted during research, whether cited in the paper or not. A reference list, on the other hand, contains only the sources cited within the text. The key difference is what gets included—everything consulted versus only what's cited.

Charts and Graphs

Since the APA manual does not give direct information for citing every type of source, including charts or graphs, they instruct you to follow the example that is most like the source you are trying to cite. 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.

APA In-Text Citations for Research Writing

Why Use In-Text Citations?

When writing a journal article, literature review, convention paper, or any other academic document, authors must include in-text citations whenever they refer to, summarize, paraphrase, or quote from another source. In addition, every time a work is cited within a paper (in APA style, a parenthetical citation), a corresponding entry must be included in the reference list.

How to Cite a Research Paper Using In-Text Citations

The rationale behind citing other people’s publications in your own manuscript is that you want to avoid intellectual dishonesty by giving credit to whoever reported a finding first or invented a specific technique. This is not only an ethical question, as being “sloppy” with your sources can easily be considered plagiarism (and even self-plagiarism , if you fail to refer to your own work), which can have legal consequences and damage your reputation.

General rules for what information should be provided when citing sources in a research paper vary across fields and depend on the type of source (e.g., books, journal articles, patents, conference proceedings, websites, etc.). We are not going into such differences here but will focus on the correct way of referencing other people’s research in your own paper according to one of the most common styles used to cite sources within the social sciences and in several other academic disciplines , that is, APA (American Psychological Association) style .

In research papers, in-text citations are most commonly used in the Introduction and Discussion Results sections. The following guidelines and examples are taken from the APA Publication Manual, 6th edition, 2nd printing , which details rules and application of APA style in research papers, including in-text citations, endnotes/footnotes, and references. For more information, consult the APA Style Manual website .

This resource provides detailed guidelines for citing sources in your paper and includes examples of in-text citations for reference by research authors. Before submitting your manuscript to a journal or publisher, be sure to use our free APA citation generator for your references and in-text citations.

APA Citation Rules: The Basics

Order and structure of in-text citation content.

When using APA format, follow the “author-date” method of in-text citation. Write the author’s last name and publication year for the source in parentheses and separate these pieces of information with a comma.

When referring to external work or referencing an entire work but not directly quoting the material, you only need to make a reference to the author and year of publication and not the page number in your citation.

The results of the first enzyme study (Chen et al., 2014) revealed several relationships.

If you mention the name of the author of the work in the sentence or earlier in the paragraph, you only need to include the year of publication in the citation.

Chen (2014) discusses several relationships revealed in this study.

Verb tense used in referring to other works

APA style requires authors to use past tense or present perfect tense (NOT present tense) when using signal phrases to refer to or discuss previous research (have a look at this article for more details on the correct tenses for different parts of a research paper ).

Radnitz (1995) found… / Radnitz (1995) has found…

Placement of in-text citations in the sentence (no quotation)

When referring to a specific work or works, place the citation (publication date only) directly after the author of the study referenced.

Klinge and Rogers (2010) found that mirroring is instrumental in developments of performative gender roles.

When giving information that reflects the results or implications of previous work, place the citation (author and publication date) at the end of the sentence.

Mirroring has been found to be instrumental in the development of performative gender roles (Klinge and Rogers, 2010).

Capitalization

Always capitalize author names and initials in in-text citations.

(r. kazinsky, 2014)    (R. Kazinsky, 2014)

In-Text Citation Rules for Short Quotations

When quoting directly from a work, include the author, publication year, and page number of the reference (preceded by “p.”).

Method 1 : Introduce the quotation with a signal phrase that includes the author’s last name; the publication year will follow in parentheses. Include the page number in parentheses at the end of the quoted text. Note that the quotation marks surround the text only, and not the parenthetical citation.

According to Khan (1976), “Graduate students tend to apply more diverse methods during their first two years of research” (p. 45). Khan (1976) noted that “graduate students tend to apply more diverse methods during their first two years of research” (p. 45), a fact that has profound implications for research departments.

Method 2 : If the author is absent in the signal phrase, include the author’s last name, the publication year, and the page number together in parentheses after the quoted text.

Researchers noted that “graduate students tend to apply more diverse methods during their first two years of research” (Khan, 1976, p. 45), but they did not offer a suggestion as to the cause.

In-text Citation Rules for Long Quotations

Long direct quotations are those with at least 40 words of quoted text in a row. Long quotes should be placed in a separate block of lines without quotation marks, similar to creating a new paragraph. Begin the quotation on a new line and indent 0.5in/1.27cm from the left margin. Type the entire quotation within these new margins using double-spacing. Include the parenthetical citation after the final punctuation mark.

Khan’s (1976) study found the following: Graduate students tend to apply more diverse methods during their first two years of research, especially when conducting research in teams of three or fewer with no senior researchers    present. This tendency could be attributed to either a misunderstanding of correct methodology or to a feeling of freedom to explore different approaches that the researchers have yet to employ. (p. 45)

Summarizing and Paraphrasing Other Works

When  paraphrasing another work , you only need to cite the author and year of publication in your in-text citation. It may be a good idea to include the page number as well if the paraphrased information is located on a specific page of the original text. APA guidelines encourage this inclusion but do not require it.

According to Khan (1976), new researchers tend to use more diverse methodologies. New researchers tend to use more diverse methodologies (Khan, 1976, p. 45).

Common Signal Phrases for Introducing External Works

• According to Johnson (publication year)…
• As Johnson (publication year) has noted…
• Johnson and Smith (publication year) contend that…
• As Johnson’s (2011) study revealed…

Citing Works by Multiple Authors/Editors

When making an in-text citation of works by multiple authors, there are specific rules to follow depending on the number of authors of a publication and the number of times you cite the same works.

Citing Multiple Works in One In-text Citation

When citing more than one source in the same in-text citation, list all sources in the standard way and separate them with a semi-colon. List the sources alphabetically (by author’s last name or by title if no author is given) in the order they appear in the reference list.

(Marsh, 1997; Johnson, 2002). (Kazinsky, 2017; “Three Different Roads,”  2013).

Citing Works by the Same Author with the Same Publication Year

When citing two or more sources with the same author and year of publication, assign lowercase letters directly after the year of publication (a, b, c) according to the alphabetical order of titles. You will use the same alphabetical designations in your in-text citations that you do in your reference list.

The incidence of West Nile virus in Florida increased between 2002 and 2004 (Dickens, 2014a). According to Dickens (2014b), “these viral infections were precipitated by record levels of rainfall around the peninsula” (p. 150).

Citing a Work Quoted in another Source

Work quoted or paraphrased in another text is called a “secondary source.” While in your reference list you must cite the primary source as well, in your in-text citation you will add the words “as cited in” followed by the secondary source. For example, if a review article by Franklin you are citing includes a useful quote by Adams that supports your paper, your in-text citation would look like this:

According to a study by Adams (as cited in Franklin, 2016), 25% of all US federal prisoners have been diagnosed with some form of social disorder. Adams (as cited in Franklin) contends that this statistic “reflects the dehumanizing conditions of most federal institutions” (p. 76).

Citing Web Pages

Entire website.

When citing an entire website (with no specific webpage or article given), simply provide the title and web address within the text of your paper. No citation is needed in the References.

The American Psychological Association includes detailed information on how to apply APA citation (http://www.apa.org).

Webpage with author(s)

A webpage with an individual author or authors should be cited in the same way as other texts, with the name or names written first, followed by the publication year.

There were 523 new cases reported in 2011 alone (Kristoff, 2012).

Webpage with a group author

Treat group authors as individual authors in in-text citations, but instead of the author’s last name, include the name of the group.

Claustrophobia afflicts one in five Britons (The Surrey Group, 2003).

Webpage with missing information

Even when some central information is missing from a website (e.g., no author, date, or webpage title), you may still cite it as a source if you use the correct formatting. For information on how to cite a website with missing information, visit the APA Style Blog post on  Missing Pieces .

Citing social media sources

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

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.

• One Author or Editor
• Two Authors or Editors
• 3-5 Authors or Editors

Using In-text Citation

Include an in-text citation when you refer to, summarize, paraphrase, or quote from another source. For every in-text citation in your paper, there must be a corresponding entry in your reference list.

APA in-text citation style uses the author's last name and the year of publication, for example: (Field, 2005). For direct quotations, include the page number as well, for example: (Field, 2005, p. 14). For sources such as websites and e-books that have no page numbers , use a paragraph number. More information on citing sources without pagination is given on the APA Style web page .

Example paragraph with in-text citation

A few researchers in the linguistics field have developed training programs designed to improve native speakers' ability to understand accented speech (Derwing, Rossiter, & Munro, 2002; Krech Thomas, 2004). Their training techniques are based on the research described above indicating that comprehension improves with exposure to non-native speech. Derwing et al. (2002) conducted their training with students preparing to be social workers, but note that other professionals who work with non-native speakers could benefit from a similar program.

Derwing, T. M., Rossiter, M. J., & Munro, M. J. (2002). Teaching native speakers to listen to foreign-accented speech.  Journal of Multilingual and Multicultural Development, 23(4), 245-259.

Krech Thomas, H. (2004).  Training strategies for improving listeners' comprehension of foreign-accented speech  (Doctoral dissertation). University of Colorado, Boulder.

Citing Web Pages In Text

Cite web pages in text as you would any other source, using the author and date if known. If the author is not known, use the title and the date as the in-text citation (for long titles just use the first few words). Your in-text citation should lead your reader to the corresponding entry in the reference list. For sources with no date use n.d. (for no date) in place of the year: (Smith, n.d.). Below are examples of using in-text citation with web pages.

Web page with author:

In-text citation :

Role-play can help children learn techniques for coping with bullying (Kraiser, 2011).

Reference entry:

Kraizer, S. (2011). Preventing bullying. Retrieved from http://safechild.org/categoryparents/preventing-bullying/

Web page with no author:

In-text citation:

The term Nittany Lion was coined by Penn State football player Joe Mason in 1904 (All things Nittany, 2006).

All things Nittany. (2006). Retrieved from http://www.psu.edu/ur/about/nittanymascot.html

Web page with no date:

Establishing regular routines, such as exercise, can help survivors of disasters recover from trauma (American Psychological Association [APA], n.d.).

American Psychological Association. (n.d.). Recovering emotionally from disaster. Retrieved from http://www.apa.org/helpcenter/recovering-disasters.aspx

General Guidelines

In-text references should immediately follow the title, word, or phrase to which they are directly relevant, rather than appearing at the end of long clauses or sentences. In-text references should always precede punctuation marks. Below are examples of using in-text citation.

Author's name in parentheses:

One study found that the most important element in comprehending non-native speech is familiarity with the topic (Gass & Varonis, 1984).

Author's name part of narrative:

Gass and Varonis (1984) found that the most important element in comprehending non-native speech is familiarity with the topic.

Group as author:

First citation: (American Psychological Association [APA], 2015) Subsequent citation: (APA, 2015)

Multiple works: (separate each work with semi-colons)

Research shows that listening to a particular accent improves comprehension of accented speech in general (Gass & Varonis, 1984; Krech Thomas, 2004).

Direct quote: (include page number)

One study found that “the listener's familiarity with the topic of discourse greatly facilitates the interpretation of the entire message” (Gass & Varonis, 1984, p. 85).

Gass and Varonis (1984) found that “the listener’s familiarity with the topic of discourse greatly facilitates the interpretation of the entire message” (p. 85).

Note:  For direct quotations of more than 40 words , display the quote as an indented block of text without quotation marks and include the authors’ names, year, and page number in parentheses at the end of the quote. For example:

This suggests that familiarity with nonnative speech in general, although it is clearly not as important a variable as topic familiarity, may indeed have some effect. That is, prior experience with nonnative speech, such as that gained by listening to the reading, facilitates comprehension. (Gass & Varonis, 1984, p. 77)

Works by Multiple Authors

APA style has specific rules for citing works by multiple authors. Use the following guidelines to determine how to correctly cite works by multiple authors in text.  See pages 174-176 of the manual.

Note: When using multiple authors' names as part of your narrative, rather than in parentheses, always spell out the word and. For multiple authors' names within a parenthetic citation, use &.

See chart on page 177 of the manual for useful information on authors.

One author: (Field, 2005)

Two authors: (Gass & Varonis, 1984)

Three to five authors:

First citation: (Tremblay, Richer, Lachance, & Cote, 2010) Subsequent citations: (Tremblay et al., 2010)

Six or more authors: (Norris-Shortle et al., 2006).

When writing a paper for a research project, you may need to cite a research paper you used as a reference. The basic information included in your citation will be the same across all styles. However, the format in which that information is presented is somewhat different depending on whether you're using American Psychological Association (APA), Modern Language Association (MLA), Chicago, or American Medical Association (AMA) style.

Citation Help

• For example: "Kringle, K., & Frost, J."

• For example: "Kringle, K., & Frost, J. (2012)."
• If the date, or any other information, are not available, use the guide at http://blog.apastyle.org/apastyle/2012/05/missing-pieces.html .

• For example: "Kringle, K., & Frost, J. (2012). Red noses, warm hearts: The glowing phenomenon among North Pole reindeer."
• If you found the research paper in a database maintained by a university, corporation, or other organization, include any index number assigned to the paper in parentheses after the title. For example: "Kringle, K., & Frost, J. (2012). Red noses, warm hearts: The glowing phenomenon among North Pole reindeer. (Report No. 1234)."

• For example: "Kringle, K., & Frost, J. (2012). Red noses, warm hearts: The glowing phenomenon among North Pole reindeer. (Report No. 1234). Retrieved from Alaska University Library Archives, December 24, 2017."

• For example: "(Kringle & Frost, 2012)."
• If there was no date on the research paper, use the abbreviation n.d. : "(Kringle & Frost, n.d.)."

• For example: "Kringle, Kris, and Jack Frost."

• For example: "Kringle, Kris, and Jack Frost. "Red Noses, Warm Hearts: The Glowing Phenomenon among North Pole Reindeer." Master's thesis."

• For example: "Kringle, Kris, and Jack Frost. "Red Noses, Warm Hearts: The Glowing Phenomenon among North Pole Reindeer." Master's thesis, Alaska University, 2012."

• For example: "Kringle, Kris, and Jack Frost. "Red Noses, Warm Hearts: The Glowing Phenomenon among North Pole Reindeer." Master's thesis, Alaska University, 2012. Accessed at http://www.northpolemedical.com/raising_rudolf."

• Footnotes are essentially the same as the full citation, although the first and last names of the authors aren't inverted.
• For parenthetical citations, Chicago uses the Author-Date format. For example: "(Kringle and Frost 2012)."

• For example: "Kringle, Kris, and Frost, Jack."

• For example: "Kringle, Kris, and Frost, Jack. "Red Noses, Warm Hearts: The Glowing Phenomenon Among North Pole Reindeer.""

• For example, suppose you found the paper in a collection of paper housed in university archives. Your citation might be: "Kringle, Kris, and Frost, Jack. "Red Noses, Warm Hearts: The Glowing Phenomenon Among North Pole Reindeer." Master's Theses 2000-2010. University of Alaska Library Archives. Accessed December 24, 2017."

• For example: "(Kringle & Frost, p. 33)."

• For example: "Kringle K, Frost J."

• For example: "Kringle K, Frost J. Red noses, warm hearts: The glowing phenomenon among North Pole reindeer."

• For example: "Kringle K, Frost J. Red noses, warm hearts: The glowing phenomenon among North Pole reindeer. Nat Med. 2012; 18(9): 1429-1433."

• For example, if you're citing a paper presented at a conference, you'd write: "Kringle K, Frost J. Red noses, warm hearts: The glowing phenomenon among North Pole reindeer. Oral presentation at Arctic Health Association Annual Summit; December, 2017; Nome, Alaska."
• To cite a paper you read online, you'd write: "Kringle K, Frost J. Red noses, warm hearts: The glowing phenomenon among North Pole reindeer. http://www.northpolemedical.com/raising_rudolf"

• For example: "According to Kringle and Frost, these red noses indicate a subspecies of reindeer native to Alaska and Canada that have migrated to the North Pole and mingled with North Pole reindeer. 1 "

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.

How to Cite Research Paper

There are several formats that are used to cite a research paper. Follow the guide for the Citation of a Research Paper:

Purpose of Research Paper Citation

The purpose of citing sources in a research paper is to give credit to the original authors and acknowledge their contribution to your work. By citing sources, you are also demonstrating the validity and reliability of your research by showing that you have consulted credible and authoritative sources. Citations help readers to locate the original sources that you have referenced and to verify the accuracy and credibility of your research. Additionally, citing sources is important for avoiding plagiarism, which is the act of presenting someone else’s work as your own. Proper citation also shows that you have conducted a thorough literature review and have used the existing research to inform your own work. Overall, citing sources is an essential aspect of academic writing and is necessary for building credibility, demonstrating research skills, and avoiding plagiarism.

Advantages of Research Paper Citation

There are several advantages of research paper citation, including:

• Giving credit: By citing the works of other researchers in your field, you are acknowledging their contribution and giving credit where it is due.
• Strengthening your argument: Citing relevant and reliable sources in your research paper can strengthen your argument and increase its credibility. It shows that you have done your due diligence and considered various perspectives before drawing your conclusions.
• Demonstrating familiarity with the literature : By citing various sources, you are demonstrating your familiarity with the existing literature in your field. This is important as it shows that you are well-informed about the topic and have done a thorough review of the available research.
• Providing a roadmap for further research: By citing relevant sources, you are providing a roadmap for further research on the topic. This can be helpful for future researchers who are interested in exploring the same or related issues.
• Building your own reputation: By citing the works of established researchers in your field, you can build your own reputation as a knowledgeable and informed scholar. This can be particularly helpful if you are early in your career and looking to establish yourself as an expert in your field.

Citation examples

This page lists the details you will need to include when writing citations for various types of source material. The examples given are in the 'Cite Them Right' version of the Harvard style.

For each example:

• Reference list  refers to the way it would be cited in your reference list or bibliography when using the 'Cite Them Right' Harvard style.
• In-text citation  refers to the way that a work would be cited either in the body of the text or in footnotes when using 'Cite Them Right' Harvard style.
• Referencing styles in use in the University Find out which style your Department uses. Please consult your course handbook for definitive guidance on which style to use.
• Styles of referencing Overview of different referencing styles in use at the University.

Note that, whatever the type of source, the title of the containing volume (i.e. the book, journal, collection etc) should always be marked out, usually by being put in italics but sometimes underlined. Whichever you use, be consistent and use the same formatting throughout your citations.

If the source you want to cite is not listed here consult the following book:

Alternatively ask your Academic Liaison Librarian or a Study Adviser for guidance:

• Contact your Academic Liaison Librarian
• Make an appointment with a Study Adviser

Elements to include:

• Authors or Editors
• Year of publication (in round brackets)
• Title (in italics)
• Edition (if applicable)
• Place published
• Series and volume number (if applicable)

• Elements to include
• Print journals or print journals now online
• Online only journals
• Versions in repositories

The information you include in the reference will depend on whether the journal is published in print (but uploaded for electronic access), only published online, or is a version found in an institutional repository. You can usually tell the difference by looking for page numbers. If each article in the journal begins at page 1, or has no page number at all, it is likely to be an online-only journal. 

• Article title (in single quotation marks)
• Journal title (in italics, capitalise the first letter of each word except linking words)
• Volume number
• Issue number (if present, in round brackets)
• Page numbers or article reference number (Include the page numbers of the whole article when writing your full citation, not just the pages you have referred to)
• DOI or web link for online-only articles

See the examples in the other tabs in this box.

Examples for articles in print copies of journal articles or a print journal accessed online (e.g. on JSTOR)

Traditionally all articles were published in print format in issues which then formed part of a volume and this way of citing them (giving volume, issue and page numbers) has been retained even though most are now available online. There is no need to include the DOI or web address for articles with volume numbers and page numbers or an article reference number even if you accessed them online.

A single author:

Reference list:   Gulddal, J. (2020) 'That deep underground savage instinct: narratives of sacrifice and retribution in Agatha Christie's Appointment with Death',  Textual Practice,  34(11), pp. 1803-1821.

In-text citation: (Gulddal, 2020)

Two authors - include them both separated by and or &:

Reference list:  Thomas, D. and Tian, L. (2021) 'Hits from the Bong: the impact of recreational marijuana dispensaries on property values',  Regional Science and Urban Economics,  87, article number 103655.

In-text citation: (Thomas and Tian, 2021)

Three authors - include them all, separate the first two with a comma and use and or & before the third author:

In-text citation: (Abu Salem, Gemail and Nosair, 2021)

Four or more authors - include them all in the full reference, but for the in-text citation you can just state the first author, followed by  et al .

Reference list: Moise, L., Gutiérrez, A.H., Khan, S., Tan, S., Ardito, M., Martin, W.D. & De Groot, A.S. (2020) 'New immunoinformatics tools for swine: designing epitope-driven vaccines, predicting vaccine efficacy, and making vaccines on demand',  Frontiers in Immunology,  11, article number 563362.

In-text citation:   (Moise  et al. , 2020)

Examples for online-only journals

If the journal is ONLY available online, you should include the DOI or the URL in the full reference. Online-only journal articles may not have page numbers or reference numbers, or pagination for each article will begin with '1'. The rules for in-text citations are the same as for print articles.

Article with a DOI:

Reference list:  Mair, A., Poirier, M. and Conway M.A. (2021) 'Age effects in autobiographical memory depend on the measure',  PLoS one,  16(10), article number e0259279. Available at: https://doi.org/10.1371/journal.pone.0259279

Article without a DOI:

Reference list: Farrell, L.G. (2013) 'Challenging assumptions about IT skills in higher education'. Journal of Learning Development in Higher Education , 6. Available at: http://www.aldinhe.ac.uk/ojs/index.php?journal=jldhe&page=article&op=view&path[]=173&path[]=138 (Accessed: 23 June 2021)

Examples for versions of articles found in repositories

Authors will often put versions of their articles into institutional repositories to comply with funding requirements to make the research Open Access. These may be pre-print versions (before peer review has taken place) or post-print versions, also known as author accepted manuscripts (the final version of the text, following peer review, to be published in the journal).

Pre-print example

Allen, R. J., Horowitz, L. W., Naik, V., Oshima, N., O'Connor, F., Turnock, S., Shim, S., Le Sager, P., Van Noije, T., Tsigaridis, K., Bauer, S. E., Sentman, L. T., John, J. G., Broderick, C., Deushi, M., Folberth, G., Fujimori, S. and Collins, B.  (2021) 'Significant climate benefits from near-term climate forcer mitigation in spite of aerosol reductions'. To be published in Environmental Research Letters  [Preprint]. Available at: http://centaur.reading.ac.uk/view/creators/90004988.html (Accessed: 24 June 2021)

For post-prints which are identical in content to the published version, you should cite the published version instead of citing the repository version.

• Chapter author(s)
• Chapter title in single quotation marks
• 'in' followed by book author(s)/editor(s)
• Book title (in italics)
• Publisher's name

Further guidance on referencing websites

Have a look at this Study Advice video tutorial (note that the format of the examples may not match the guidance given above):

• Referencing websites (video) Watch this brief video tutorial for more on the topic.
• Referencing websites (transcript) Read along while watching the video tutorial.

A secondary reference is used when you are referring to a source which you have not read yourself, but have seen quoted or read about in another source.  Where possible, you should always try to read the original of anything you wish to refer to ; otherwise you are relying on the author who cited the reference to have interpreted it correctly and not taken it out of context. Use the reference list at the end of the source you are reading to find details of the reference and search for it using the search boxes below.

Find books using the Enterprise catalogue

Just type in the first author's surname and a few words from the title.

Find journal articles using Summon

Just type in the first author's surname and first part of the article title.

If you can't get hold of the original source you'll need to do a secondary reference and you should make clear that you are not using the original source. Only include the source you have used in your list of references following the guidance for citing that type of publication. 

Different Schools/Departments might have different preferred ways of doing this, so do check any advice you are given or ask your course tutor if you are not sure. Otherwise, this is general guidance.

If the author quotes another source:

F rance (2003, quoted in Weingart et al ., 2018, p. 24) provides evidence that hospitals use internal reporting procedures to identify...

In-text citation: (University of Reading, 2022)

Table taken directly from another source

Tables should be sequentially numbered in your work with the title above the table - as in the following example in the Harvard referencing style. When referring to the table in your writing use the table number. 

A citation should be included at the end of the table title and a full citation added to your reference list for the source. 

Example of referring to a table in a sentence:

The macronutrient content of the diets used in the study is shown in Table 2. 

Mitchell, N.S. and Ard, J.D. (2021) 'Weight loss, lifestyle, and dietary factors in cardiovascular diseases in African Americans and Hispanics', in Ferdinand, K.C., Taylor, H.A. and Rodriguez, C.J. (eds)  Cardiovascular disease in racial and ethnic minority populations . Cham: Humana Press, pp. 167-182.

Table you have compiled yourself from multiple sources

If you are taking information from multiple sources and compiling your own table you still need to acknowledge those sources. 

Once again your table will need to be numbered in sequence with other tables in your work and have a title. For example:

Table 1: Turnover of Tesco PLC 2017-2021

You can then add a, b, c etc next to the statistics in the table (or the columns depending on how your data is arranged, see the example linked below) and then add a matching lettered list of citations for the sources at the bottom of the table:

Sources: a Tesco PLC (2017); b Tesco PLC (2018) etc

 Then in your reference list the end of your work, you would add the full reference for each source. For example:

Tesco PLC (2017)  Annual report and financial statement . Available at:  https://www.tescoplc.com/investors/reports-results-and-presentations/reports-archive/  (Accessed: 10 November 2022).

Tesco PLC (2018) Annual report and financial statement . Available at:  https://www.tescoplc.com/investors/reports-results-and-presentations/reports-archive/  (Accessed: 10 November 2022).

 See the following example where a & b has been added to the columns, as everything in that column has come from the same source:

• Example of citing multiple sources used in a table

The other option is to arrange it with the brief citations in the table. See Table 1 in the following example. The full references would go into your reference list at the end of the work in the same way as Method 1.

• How to cite sources in a table (Method 2) This example is in the APA referencing style but the same approach would work with Harvard.

It is strongly recommended that you use published sources such as books and journal articles in your assignments instead of materials posted by academics on Blackboard. Always check with the academic who has set the assignment whether you are allowed to include citations for their materials in your work.
