APA Style Guide

APA Style is a set of guidelines developed by the American Psychological Association to help writers consistently format papers and document sources.

The following APA citation examples are based on the 7th edition of the Publication Manual of the American Psychological Association and the Concise Guide to APA Style. Copies of both guides are available in the Reference room (REF BF76.7 .P83 2020 and REF BF76.7 .C66 2020).

    In-text Citations

    A writer must document all information and ideas taken from others, whether quoting that source or putting it in your own words. To do this, you can use in-text citations which point your reader to the exact source on your Reference list, as well as the location within that source. APA uses an author-date style for in-text citations. Parenthetical citations include the author's surname(s) and the year of publication. Use n.d. if no date given. 

    Parenthetical Citation Examples

    • One author: (McGuinness, 2019) 
    • Two authors: (Denning & Little, 2017)
    • Three or more authors: (Lim et al., 2019)
    • Group author: (World Health Organization, 2018)
    • No author: (“Gay Rights Are Civil Rights,” 2020)

    Narrative citations include the author's name in the sentence, immediately followed by the date in parentheses.

    Example: According to the World Health Organization (2018), gaming addiction…


    APA recommends paraphrasing sources taken from others by putting them in your own words. Quoting sources word for word should be limited to reproducing an exact definition, or capturing an author’s exact wording because it was memorable or in order to respond to it. Add page numbers to your in-text citations for direct quotes (p. or pp. for multiple pages). When a work has no author, use the first few words of the title. Put quotation marks around the title of an article or chapter, and italicize the title of a periodical or book.

    Short Quotations (Fewer than 40 Words)

    Enclose the quotation with double quotation marks, and place the author(s), the year of publication, and the page number of the quoted text in parentheses immediately at the end of your quote, preceding the closing punctuation.

    Parenthetical citation for a short direct quote

    “The heart of patient-centered care is sensitive face-to-face communication” (Lim et al., 2018, p. 17).

    Narrative citation for a short direct quote

    According to Lim et al. (2018), “The heart of patient-centered care is sensitive face-to-face communication” (p. 17).

    Block Quotations (40 or More Words)

    Place the quotation in a block, indented five spaces from the left margin. Do not use quotation marks. The parenthetical documentation follows the closing punctuation. Use double spacing, as in the rest of your paper.


    Start your reference list at the top of a new page. Entries are arranged alphabetically and double-spaced. Use a hanging indent for citations in the reference list, so the reader of your paper can easily scan the list to locate a specific citation in your paper. Every recoverable source cited in your paper should be included on your reference list, and every source on your reference list should be cited at least once in your paper.
