About APA Style

APA Style is a popular style among the social sciences. When editors or teachers ask you to write in APA Style they are referring to the editorial style that many of the social and behavioral sciences have adopted to present written material in the field. APA Style was first developed in 1929 by a group of social scientists who wished to establish sound standards of communication. Since that time, it has been adopted by leaders in many fields and has been used by writers around the world.

In-Text Citations

There are several ways to cite a quotation within a document with APA format, but the same citation information (author’s last name, publication date and page number) must be included. The Publication Manual of the American Psychological Association (6th ed.) gives the following examples:

Quotation 1 - use double quotations:  
When author is mentioned in the beginning:
Miele (1993) found that "the 'placebo effect', which had been verified in previous studies, disappeared when [only the first group's] behaviors were studied in this manner" (p.276)

When author is mentioned at the end:
... "the 'placebo effect', which had been verified in previous studies, disappeared when [only the first group's] behaviors were studied in this manner" (Miele, 1993, p. 276)

Quotation 2 - block quotation of 40 words or more; no quotation marks used; indent 5 spaces from the left margin:
Miele (1993) found the following:

The “placebo effect,” which had been verified in previous studies, disappeared when behaviors were studied in this manner.  Furthermore, the behaviors were never exhibited again [emphasis added], even when reel [sic] drugs were administered. Earlier studies (e.g., Abdullah, 1984; Fox, 1979) were clearly premature in attributing the results to a placebo effect. (p. 276)

The publication manual also notes that sometimes electronic sources (such as an HTML full-text document from an online database or information from a website) do not have page numbers. If no page numbers are listed, use the paragraph number and, when given, the heading or section title. The manual provides the following two examples:

Quotation 1 - when paragraph numbers are visible, indicate with (para.):
Basu and Jones (2007) went so far as to suggest the need for a new "intellectual framework in which to consider the nature and form of regulation in cyberspace" (para. 4).

Quotation 2 - document uses headings rather than paragraphs or page numbers:
In their study, Verbunt, Pernot, and Smeets (2008) found that "the level of perceived disability in patients with fibromyalgia seemed best explained by their mental health condition and less by their physical condition" (Discussion section, para.1).

Quotation 3 - when headings are too unwieldy to cite in full, use a short parenthetical title enclosed in quotation marks:
"Empirical studies have found mixed results on the efficacy of labels in educating consumers and changing consumption behavior" (Golan, Kuchler, & Krissof, 2007, "Mandatory Labeling has Targeted", para. 4).

References List

"APA Style provides a foundation for effective scholarly communication because it helps writers present their ideas in a clear, precise, and inclusive manner."
