What is APA Style?
(Developed by Dr. Marcy Goldsmith and the Librarian at Tufts University.)
APA style was developed and is maintained by the American Psychological Association (APA). It is heavily used by the social sciences, behavioral sciences, and many other disciplines.
Features: Focuses on dates the study was published; page numbers may also be cited. Features in-text parenthetical citations of author(s) and date: (Smith, 1998). A page number also must be added for quotes taken from a specific page: (Smith, 1998, p. 123). Endnotes or footnotes may be used to add supplementary comments.
