How to Cite a Research Paper in APA

If you’re citing a research article or paper in APA style, you’ll need to use a specific citation format that varies depending on the source. Assess whether your source is an article or report published in an academic journal or book, or whether it is an unpublished research paper, such as a print-only thesis or dissertation. Either way, your in-text citations will need to include information about the author (if available) and the date when your source was published or written.

Writing an In-Text Citation

Download Article

1
Name the author and the publication date in-text before a quote. To simplify the in-text citation, place the last name of the author in the text to introduce the quote and then the publication date for the text in parentheses. You can then leave the author’s name and the publication date out of the quote itself.^{[1]XResearch source}
- For example, you may write, “Gardener (2008) notes, ‘There are several factors to consider about lobsters’ (p. 199).”
2
Include the author’s last name in the citation if you don’t list it in-text. If you do not want to name the author in the text, start the citation with their last name in parentheses at the end of the quote or the information you wish to cite. If there is more than one author, list their last names, separated by commas.^{[2]XTrustworthy SourcePurdue Online Writing LabTrusted resource for writing and citation guidelinesGo to source}
- For example, you may write, “‘There are several factors to consider about lobsters’ (Gardner, 2008, p. 199).” Or, “The paper claims, ‘The fallen angel trope is common in religious and non-religious texts’ (Meek & Hill, 2015, p.13-14).”
- For articles with 3-5 authors, write out the names of all the authors the first time you cite the source. For example: (Hammett, Wooster, Smith, & Charles, 1928). In subsequent citations, write only the first author’s name, followed by et al.: (Hammett et al., 1928).
- If there are 6 or more authors for the paper, include the last name of the first author listed and then write "et al." to indicate that there are more than 5 authors.
- For example, you may write, "'This is a quote' (Minaj et al., 1997, p. 45)."

Write the name of the organization if there is no author. If you are quoting from a research paper or article with no author, look for the name of the organization that published the paper.^{[3]XTrustworthy SourcePurdue Online Writing LabTrusted resource for writing and citation guidelinesGo to source}
- For example, you may write, “‘The risk of cervical cancer in women is rising’ (American Cancer Society, 2012, p. 2).”
4
Use 1-4 words from the title in quotation marks if there is no author or organization. If you cannot find an author or an organization that published the paper, you can use the first 1-4 words of the title of the paper instead.^{[4]XResearch source}
- For example, you may write, “‘Shakespeare may have been a woman’ (“Radical English Literature,” 2004, p. 45).” Or, “The paper notes, ‘There is a boom in Virgin Mary imagery’ (“Art History in Italy,” 2011, p. 32).”
5
Include the year of publication for the paper. Place a comma between the author or title of the paper and the publication date.^{[5]XResearch source}
- For example, you may write, “‘There are several factors to consider about lobsters’ (Gardner, 2008, p. 199).” Or, “The paper claims, ‘The fallen angel trope is common in religious and non-religious texts’ (“Iconography in Italian Frescos,” 2015, p.13-14).”
if you cannot find the date. For example, you may write, “‘Shakespeare may have been a woman’ (“Radical English Literature," n.d., p. 12).”.” Or, “Minaj (n.d., p. 45) notes, ‘The study of psychology has been underfunded.’”^{[6]XResearch source}
7
Note the page number where the quote or information appears in the paper. Write “p.” for page number and place a dash between the numbers if the quote or information you are citing spans more than 1 page.^{[7]XTrustworthy SourcePurdue Online Writing LabTrusted resource for writing and citation guidelinesGo to source}
- For example, you may write, “‘There are several factors to consider about lobsters’ (Gardner, 2008, p. 199).” Or, “The paper claims, ‘The fallen angel trope is common in religious and non-religious texts’ (“Iconography in Italian Frescos,” 2015, p.145-146).”
8
Use “para.” if there are no page numbers in the research paper. Count the paragraphs in the paper and number them in order. Then, indicate which numbered paragraph the quote or information appears in by writing “para” and the number.^{[8]XResearch source}
- For example, you may write, “‘The effects of food deprivation are long-term’ (Mett, 2005, para. 18).”

Creating a Reference List Citation for a Published Source

1
Determine that your source is published. There are a variety of ways to find out whether your source is considered “published.” One of the easiest is to look at the title page, header, or footer of the source for publication information. For example, if you’re citing a chapter from a book, check the title page for information about publishing company and the place and date of publication.
- Material on websites is also considered “published,” even if it’s not peer-reviewed or associated with a formal publishing company.
- While academic dissertations or theses that are print-only are considered unpublished, these types of documents are considered published if they’re included in an online database (such as ProQuest) or incorporated into an institutional repository.
2
Note the author of the paper by last name and first 2 initials. Place a comma between the author's full last name and their first and second initials (if you know them). If there are multiple authors, list them by last name and then their initials, separated by a comma.^{[9]XResearch source}
- For example, you may write, “Gardner, L. M.” Or, “Meek, P. Q., Kendrick, L. H., & Hill, R. W.”
- If there is no author, you can list the name of the organization that published the research paper. For example, you may write, “American Cancer Society” or “The Reading Room.”
- Formally published documents that don’t list an author or that have a corporate author are typically reports or white papers.
3
Include the year the paper was published in parentheses, followed by a period. Put a period between the author or organization name and the publication year for the research paper or article.^{[10]XResearch source}
- For example, you may write, “Gardner, L. M. (2008).” Or, “American Cancer Society. (2015).”

List the title of the paper. Include the entire title of the research paper or article in the citation.^{[11]XTrustworthy SourcePurdue Online Writing LabTrusted resource for writing and citation guidelinesGo to source} If you’re citing an article that was published in a periodical or as part of an edited book, don’t put the title in quotes or italics.

Include the website where you retrieved the paper if it is web-based. If you accessed a research paper online, note this in the citation by including “Retrieved from.” Write the organization or publication’s name, followed by the URL for the paper.^{[15]XTrustworthy SourcePurdue Online Writing LabTrusted resource for writing and citation guidelinesGo to source}
- For example, you may write, “Kotb, M. A., Kamal, A. M., Aldossary, N. M., & Bedewi, M. A. (2019). Effect of vitamin D replacement on depression in multiple sclerosis patients.

Citing Unpublished Sources in Your Reference List

Download Article

1
Determine that your source is unpublished. You’ll need to cite unpublished research papers a little differently from published ones. First, make sure that your source is definitely considered unpublished. You’ll also need to check that you’re allowed to use unpublished or non-peer-reviewed sources in your writing assignment. Types of unpublished papers include:
- Print-only dissertations or theses.
- Articles or book chapters that are in press or have been recently prepared or submitted for publication.
- Papers that have been rejected for publication or were never intended for publication (such as student research papers or unpublished conference papers).
2
Indicate the status of papers that are in the process of publication. If you’re citing a source that’s on its way to being published, you’ll need to show in your citation where it is in the publication process. Include the name of the author, the title of the paper, and a note regarding the status of the paper.^{[16]XResearch source}
- If the paper is currently being prepared for publication, include the author’s name, the year when the current draft was completed, and the title of the article in italics, followed by “Manuscript in preparation.” For example: Wooster, B. W. (1932). What the well-dressed man is wearing. Manuscript in preparation.
- If the paper has been submitted for publication, format the citation the same way as if it were in preparation, but instead follow the title with “Manuscript submitted for publication.” For example: Wooster, B. W. (1932). What the well-dressed man is wearing. Manuscript submitted for publication.
- If the paper has been accepted for publication but is not yet published, replace the date with “in press.” Do not italicize the paper title, but do include the title of the periodical or book in which it will be published and italicize that. For example: Wooster, B. W. (in press). What the well-dressed man is wearing. Milady’s Boudoir.
3
Note the status of papers that were never intended for publication. In some cases, you may need to cite a paper that was never submitted or accepted for publication. In these situations, provide the name of the author, the date of writing or presentation, the title (in italics), and the context of the paper (i.e., where and for what purpose it was written). For example:^{[17]XTrustworthy SourcePurdue Online Writing LabTrusted resource for writing and citation guidelinesGo to source}
- If the paper was written for a conference but never published, your citation should look like this: Riker, W. T. (2019, March). Traditional methods for the preparation of spiny lobe-fish. Paper presented at the 325th Annual Intergalactic Culinary Conference, San Francisco, CA.
- For an unpublished paper written by a student for a class, include details about the institution where the paper was written. For example: Crusher, B. H. (2019). A typology of Cardassian skin diseases. Unpublished manuscript, Department of External Medicine, Starfleet Academy, San Francisco, CA.
4
Clarify the status of unpublished dissertations and theses. If you cite an academic thesis or dissertation that is only available as a print source, you’ll need to indicate that it is unpublished. Include the name of the author, the date of completion, and the title of the dissertation or thesis in italics. Follow the title with “(Unpublished doctoral dissertation).” Complete the citation with information about the university where the dissertation or thesis was produced.^{[18]XTrustworthy SourcePurdue Online Writing LabTrusted resource for writing and citation guidelinesGo to source}
- For example, you may write, “Pendlebottom, R. H. (2011). Iconography in Italian Frescos (Unpublished doctoral dissertation). New York University, New York, United States.”
