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 "

Why are citations important?

Apa citations.

Good research projects combine data from a variety of sources and carefully document the sources of information and ideas. Research documentation usually appears in two parts: short in-text citations occurring within the actual paper and a longer, complete list of works at the end of the paper called a bibliography, reference list, or works cited page. 

Besides giving credit to the source of information or ideas, there are other great reasons to cite in your research project:

• Persuasiveness - Your writing will be more persuasive if you cite the research on which you based your own conclusions and arguments.
• Sharing - Citations make it possible for your professor and other readers to examine interesting sources that you found.
• Communication -  Correct citations helps you communicate effectively with potential peers within a discipline.
• Skills -  Correct citation demonstrates your research and documentation abilities to your professor.
• Avoid Plagiarism -  Correct citation use helps protect you from plagiarizing.

Note: a hyperlink or URL included in the text is not the same as a citation. Ex: "Higher gas prices are on the way (cnn.com/specialreport)." URLs in the text, while common on the internet, are not considered a correct form of scholarly citation.

Using Information Legally and Ethically

Citing resources is common practice for writers engaged in any type of research. By providing citations, the writer is contributing to the ongoing scholarly discussion of the topic. Properly cited resources:

• Attribute credit where credit is due
• Provide credibility for your arguments
• Demonstrate evidence of your research
• Offer a path for your readers for ongoing scholarship
• Help avoid plagiarism

The legal and ethical issues surrounding the use of information goes beyond avoiding plagiarism and properly citing sources .

Researchers should be knowledgable about isses related to:

• freedom of speech
• intellectual property
• billions of pages of web content,
• millions of pages of proprietary content from subscription publications, and
• over 80 million student papers previously submitted to Turnitin.

Easy-to-read Originality Reports help teach students about proper citation and ensure their academic integrity.

Your instructor may choose to use the T urnitin service which is embedded within the Canvas course management system.

What are Citations?

Choosing a Citation Style

Various disciplines have preferred citation styles, depending, usually, on which bits of information about sources is most relevant to researchers. Commonly used styles are:

• APA (American Psychological Association) -  used in   psychology, education, and other social sciences (See  Basics of APA Style  tutorial.)
• MLA (Modern Language Association) -  used in literature, arts, and humanities
• Chicago -  used in the humanities and social sciences
• Turabian -   based on Chicago style, and designed for students to use with all subjects - used in many disciplines in humanities, social sciences and natural sciences
• APSA (American Political Science Association) -  used in political science ( APSA Style Manual )
• ACS (American Chemical Society)  - used in chemistry
• CSE (Council of Science Editors)  - used in biology

Your instructor may want you to use a particular style. When in doubt, ask.

The following style guide books are available on reserve at the Library Services Desk. They can be checked out for use in the Library only.

• APA ( Publication manual of the American Psychological Association , 6th ed.)
• MLA ( MLA handbook for writers of research papers , 7th ed.)
• Chicago style ( The Chicago Manual of Style , 16th ed.)
• Turabian ( A Manual for Writers of Research Papers, Theses, and Dissertations,  2013)

General Format Guidelines for Scholarly Articles

What is a DOI (digital object identifier)??

• the DOI system provides persistent identification for managing digital content.
• if a DOI is available, it is used in place of a URL.  
• DOI numbers can often be found on the first page of an online source, or with the article's bibliographic information on the item record page.
• DOIs are now displayed as permanent URLs: http://dx.doi.org/10.1037/a0024996

For more information, see "The DOI System" (p. 5) in  APA Style Guide to Electronic References .

Sample Citations - Scholarly Articles

Journal Article with DOI (Digital Object Identifier):

All of the following are currently considered correct DOI display guidelines:

• https://doi.org/10.1037/arc0000014​
• http://dx.doi.org/10.1037/arc0000014
• doi:10.1037/arc0000014

If you consulted the article in print, you do not need to include a DOI or URL. 

Journal Article without a DOI (when DOI is not available):

If no DOI is assigned to the online content, include the URL for the journal home page.

Use this format: Retrieved from http://xxxx 

No retrieval date is needed because the journal article content will not change over time.  

Journal Article With Seven or More Authors

When a reference has 1-7 authors, spell out all authors' names in the reference list citation. If a source has 8 or more authors, list the first six, insert an ellipses, and then provide the name of the final author.

Example (article with 8 or more authors) :

In-Text Citations: The Basics

Welcome to the Purdue OWL

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

APA (American Psychological Association) style is most commonly used to cite sources within the social sciences. This resource, revised according to the 6 th edition, second printing of the APA manual, offers examples for the general format of APA research papers, in-text citations, endnotes/footnotes, and the reference page. For more information, please consult the Publication Manual of the American Psychological Association , (6 th ed., 2 nd printing).

Note:  This page reflects APA 6, which is now out of date. It will remain online until 2021, but will not be updated. The equivalent APA 7 page can be found here .

Reference citations in text are covered on pages 169-179 of the Publication Manual. What follows are some general guidelines for referring to the works of others in your essay.

Note:  On pages 65-66, the Publication Manual suggests that authors of research papers should use the past tense or present perfect tense for signal phrases that occur in the literature review and procedure descriptions (for example, Jones (1998) found or Jones (1998) has found ...). Contexts other than traditionally-structured research writing may permit the simple present tense (for example, Jones (1998)  finds ).

APA citation basics

When using APA format, follow the author-date method of in-text citation. This means that the author's last name and the year of publication for the source should appear in the text, for example, (Jones, 1998), and a complete reference should appear in the reference list at the end of the paper.

If you are referring to an idea from another work but NOT directly quoting the material, or making reference to an entire book, article or other work, you only have to make reference to the author and year of publication and not the page number in your in-text reference. All sources that are cited in the text must appear in the reference list at the end of the paper.

In-text citation capitalization, quotes, and italics/underlining

• Always capitalize proper nouns, including author names and initials: D. Jones.

( Note: in your References list, only the first word of a title will be capitalized: Writing new media .)

• When capitalizing titles, capitalize both words in a hyphenated compound word: Natural-Born Cyborgs .
• Capitalize the first word after a dash or colon: "Defining Film Rhetoric: The Case of Hitchcock's Vertigo ."
• Italicize the titles of longer works such as books, edited collections, movies, television series, documentaries, or albums: The Closing of the American Mind ; The Wizard of Oz ; Friends .
• Put quotation marks around the titles of shorter works such as journal articles, articles from edited collections, television series episodes, and song titles: "Multimedia Narration: Constructing Possible Worlds;" "The One Where Chandler Can't Cry."

Short quotations

If you are directly quoting from a work, you will need to include the author, year of publication, and page number for the reference (preceded by "p."). Introduce the quotation with a signal phrase that includes the author's last name followed by the date of publication in parentheses.

According to Jones (1998), "Students often had difficulty using APA style, especially when it was their first time" (p. 199).

Jones (1998) found "students often had difficulty using APA style" (p. 199); what implications does this have for teachers?

If the author is not named in a signal phrase, place the author's last name, the year of publication, and the page number in parentheses after the quotation.

She stated, "Students often had difficulty using APA style" (Jones, 1998, p. 199), but she did not offer an explanation as to why.

Long quotations

Place direct quotations that are 40 words or longer in a free-standing block of typewritten lines and omit quotation marks. Start the quotation on a new line, indented 1/2 inch from the left margin, i.e., in the same place you would begin a new paragraph. Type the entire quotation on the new margin, and indent the first line of any subsequent paragraph within the quotation 1/2 inch from the new margin. Maintain double-spacing throughout. The parenthetical citation should come after the closing punctuation mark.

Students often had difficulty using APA style, especially when it was their first time citing sources. This difficulty could be attributed to the fact that many students failed to purchase a style manual or to ask their teacher for help. (p. 199)

Summary or paraphrase

If you are paraphrasing an idea from another work, you only have to make reference to the author and year of publication in your in-text reference, but APA guidelines encourage you to also provide the page number (although it is not required).

According to Jones (1998), APA style is a difficult citation format for first-time learners.

APA style is a difficult citation format for first-time learners (Jones, 1998, p. 199).

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.

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 .

Standard Format of Reference Entry

All formats from the end appear identical, except for the issue date. Keep in mind the following requirements when citing a source in a research article:

• You should not count the cover page and any reference list page number in your assignment
• Your assignment should be at least ten to twelve pages
• At least cite eight sources in the article that should be dated from 2002 or after, preferably with volume number, chapter title, and website title.
• Add five peer-reviewed journal publications with the year of publication.
• You must use APA formation style, since footnotes are not permitted when citing sources;
• Before turning in the assignment, don't forget to proofread it again for mistakes like punctuation marks, use of proper nouns, and mention of publication page numbers and headings.

Start writing research article citations in alphabetical order, beginning with only the name or author's surname, followed by the book title, website, or organization. Lines must be indented, even those contained in text citation takes, inside a single reference. These are a few instances:

• Unites States. Literature Journal Department. Digital Article Review, 2 Vols. New York: Literature- Journal's Department, 2005.
• John Stan, B. (2007, May 23). Aerial Yoga. Retrieved from direct URL

How to cite an online source in journal articles.

Learn about the many citation styles developed with this goal in mind to comprehend how to cite references in a journal article. For instance, liberal sciences use the Modern Language Association's (MLA) writing style, which was established for document layout, episode title, and source citation. The structure is followed by students writing English-language academic papers in Canada, the USA, and other nations. The following are some features of MLA, APA, and other citation styles:

APA Citation Style

Use APA Style if you are unsure of when to employ in-text citations. It references the guidelines published by the American Psychological Association to record references online documents and facilitate their comprehension. You must provide an in-text citation whenever you paraphrase or summarise a source.

For a reference page: "Establishing a regular practice, like exercising, can aid patients in their recovery from a sickness." APA, n.d. (American Psychological Association). Use an APA style citation maker to simplify your work. It may handle any task involving the creation of in-text citations or a complete reference that adheres to the criteria, including:

• The proper citation of the author's name;
• The author's name in the paragraph or in the parenthetical citations that follows the excerpt that is being referenced;
• The name of the referenced authority should be followed by the publication date.

Students can also use page numbers to denote specific information in certain parts of a publication. Still, a page range usually is only used for direct quotations in APA style when a passage, or another component of the conference paper, is duplicated verbatim in a new research paper. For making appropriate reference list entries, you should follow APA guidelines.

MLA Citation Styles

• Citations are concise and clear;
• When referencing the work of another author, include a parenthetical citation.
• The following lines should be four to seven spaces from the left margin rather than being indented from it for every new line;
• List each alphabetically and sort them by source name or the author's last name;
• When writing the names of sources, capitalize all words except articles, prepositions, and conjunctions.

Use a professional MLA Generator to hasten the creation of the bibliography and citation list for your research paper. There are many free MLA citation and reference generators available for research papers. When using them, you ought to take the following actions:

• Select the type of source: scholarly articles, books, websites, newspapers, magazines, or movies. 
• Add the author's and the publication's name, the title, the place, the edition, and the type of recording; 
• After entering the relevant information, simply select "produce citation" to get it in the ideal format.

Simply use MLA style formatting , which does not require the URL or link, if citing information from a journal title a website is necessary. However, the professors do occasionally request it. Remember to reference sources in-text using the footnote format. Full citation examples include "Germany."International Affairs, US Department of State, Commute, 11 October 2012. Web. 5 March 2014.

Notes & Bibliography Style

You must use a higher number or superscript for this style. Often, these are used in complete sentences. With this technique, you can alert readers that a sentence incorporates information from another source. Each superscript links to an article title and a remark in the endnotes or footnotes.

The footnotes,  bibliography , and author-date style citation formats are the same for all sources. The in-text reference is the only difference. In the latter, the author's last name and the year of publication are mentioned in-text rather than with a corresponding superscript.

The writing style is crucial for all assignments, including essays, theses, and research papers. There are many ways to cite a source, but the APA and MLA forms and their modifications are the most basic format often used. Pick out one, then use it on the papers. Likewise, keep the same format in mind for internal citations. The reader could be confused by the text if documentation styles and formats are mixed.

You must follow the guidelines if you are a student, but if you don't have enough time for a research project, utilize the online version of a professional research paper writing service . Obtain your work with minimum effort and good quality. Qualified authors will write it, and it will be completed on schedule.
