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.

Referencing a Research Paper

  1. In APA style, cite the paper: Last Name, First Initial. (Year). Title. Publisher.
  2. In Chicago style, cite the paper: Last Name, First Name. “Title.” Publisher, Year.
  3. In MLA style, cite the paper: Last Name, First Name. “Title.” Publisher. Year.

  1. In APA style, the author's name is inverted, meaning you list the last name first. Place a comma after the last name, then the first initial. Separate the names of multiple authors with commas, using an ampersand (&) before the last name. [1]
    • For example: "Kringle, K., & Frost, J."
  2. If the paper was published in an academic journal, include the year in parentheses after the authors' names. If the paper was unpublished, such as a print-only thesis or dissertation, use the year the paper was written. [2]

  3. Use sentence capitalization to write out the full title of the research paper, capitalizing the first word and any proper names. If it has a subtitle, place a colon and capitalize the first word of the subtitle. [3]
    • 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)."
  4. If the paper was published in an academic journal or magazine, use the same format that you would for any other article . For unpublished articles, provide as much information as possible to direct your readers to the research paper. [4]
    • 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."
  5. When you write a statement that comes from the research paper, include the last names of the authors along with the year the paper was published or written. [5]
    • For example: "(Kringle & Frost, 2012)."
    • If there was no date on the research paper, use the abbreviation n.d. : "(Kringle & Frost, n.d.)."

  1. Invert the first author's name so that the last name appears first. Subsequent authors' names should be written in regular order. Spell out first names. Use a middle initial if it is provided on the research paper. [6]
    • For example: "Kringle, Kris, and Jack Frost."
  2. The title of the paper is written in title case, meaning that most adjectives, nouns, and verbs are capitalized, but articles and conjunctions are not. Titles are enclosed in quotation marks. Include the type of paper after the title. [7]
    • For example: "Kringle, Kris, and Jack Frost. "Red Noses, Warm Hearts: The Glowing Phenomenon among North Pole Reindeer." Master's thesis."
  3. If the paper was unpublished, the date you use will be the year the paper was written. If the paper was published, you'll follow the general rules for citing an article in Chicago style. [8]
    • For example: "Kringle, Kris, and Jack Frost. "Red Noses, Warm Hearts: The Glowing Phenomenon among North Pole Reindeer." Master's thesis, Alaska University, 2012."
  4. If you accessed the paper online, you should add a direct URL so your readers can go directly to the paper as you found it. If the paper has a database number assigned to it, that can also help readers locate the paper more easily. [9]
    • 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 https://www.northpolemedical.com/raising_rudolf."
  5. Chicago and Turabian (a simplified version of Chicago style) style research papers may use either footnotes or parenthetical citations to cite references in the body of your paper. [10]
    • 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)."

MLA

  1. Invert the names of the authors so that you list their last names first, followed by their first names. Spell out first names. Separate multiple authors with commas. [11]
    • For example: "Kringle, Kris, and Frost, Jack."
  2. In MLA, enclose the title and subtitle in quotation marks. Capitalize most words, but not short articles or conjunctions unless they are the first word of the title or subtitle. [12]
    • For example: "Kringle, Kris, and Frost, Jack. "Red Noses, Warm Hearts: The Glowing Phenomenon Among North Pole Reindeer.""
  3. MLA operates on the concept of containers . Your paper is part of a larger whole, which may be part of an even larger whole. In your citation, list the smallest container first, followed by the larger, all the way up to the largest. [13]
    • 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."
  4. After you mention something in your paper that requires you to cite the research paper, place the names of the authors in parentheses along with the page number where the information appears. [14]
    • For example: "(Kringle & Frost, p. 33)."

  1. An AMA citation begins with the names of the authors or editors of the paper. Use no punctuation apart from a comma between names. If there are more than 6 authors, list the first 3 followed by the abbreviation "et al." [15]
    • For example: "Kringle K, Frost J."
  2. In sentence case, you only capitalize the first word and any proper nouns included in the title of the article. If there is a subtitle, include it after a colon with an initial capital at the beginning of the subtitle. [16]
    • For example: "Kringle K, Frost J. Red noses, warm hearts: The glowing phenomenon among North Pole reindeer."
  3. A research paper that was published in an academic journal should be treated like any other journal article. Include the abbreviated title of the journal in italics, followed by the year of publication, issue number, and pages where the paper appears.
    • For example: "Kringle K, Frost J. Red noses, warm hearts: The glowing phenomenon among North Pole reindeer. Nat Med. 2012; 18(9): 1429-1433."
  4. If the paper was presented at a conference or symposium, include information about the conference where it was presented. If you found it online, provide a direct link and the date you accessed it.
    • 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. https://www.northpolemedical.com/raising_rudolf"
  5. For in-text citations, include a superscript number after the information for which you need a citation. You'll build your bibliography as you write your paper, with your citations listed in the order they are noted in your text.
    • 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 "

    At the bottom of your report, you would write a bibliography. That would have the name of the article and website. If you mean when do you need to reference it in the middle of the report, you would write something like: "Johnny Appleseed from the Antarctica Daily says...".
