Citing sources, APA style

The American Psychological Association recommends an author-date system of citations. Here, very briefly, is how the author-date system usually works.

  1. The source is introduced by a signal phrase that includes the last names of the authors followed by the date of publication in parentheses.

  2. The material being cited is followed by a page number in parentheses.

  3. At the end of the paper, an alphabetized list of references gives complete publication information about all the references the writer cites in the text of the paper. The list is arranged alphabetically by authors’ last names.

In-text citation

As researchers Yanovski and Yanovski (2002) have explained, obesity was once considered “either a moral failing or evidence of underlying psychopathology” (p. 592).
