APA has published an updated edition of their Publication Manual as of October 2019.
Please review the Publication Manual for the American Psychological Association (7th edition) for full and complete citation guidelines.
APA (American Psychological Association) style is most commonly used to cite sources within the social sciences. This resource, based on the 6th edition, second printing of the APA manual, offers examples for the general formatting of in-text and reference citations.
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.
**The in-text citation for works with three or more authors is now shortened right from the first citation. You only include the first author’s name and “et al.” (Taylor et al., 2018)**
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
(Note: in your References list, only the first word of a title will be capitalized: Writing new media.)
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.
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.
Jones's (1998) study found the following:
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).
