APA Documentation System

    The system of documentation adopted by the American Psychological Association of America (APA) consists of two components:
 
1. At the end of each passage in the text that requires documentation, the last name of the author is inserted in parentheses, followed by a comma and the year of publication. Page numbers are included only for material within quotation marks.
2.  At the end of the paper, a complete bibliographical entry is provided for each source.These entries are arranged alphabetically on a separate page under the heading References.
1.  The Parenthetical Citation
A typical citation follows the last word of the passage (or the closing quotation marks) and precedes the final punctuation.
For example:
. . . regarding the problem (Jones, 1981).
. . . no easy solution” (Jones, 1981, p. 222).
If the name of the author is introduced in the text of the paper, it is deleted from the citation to avoid unnecessary repetition.  In addition, the year (and page number for a quote) is included immediately after the name of the author.
For example:  Jones (1981) has a similar view of the problem.  He believes that . . . appropriate solution.
If more than one work of a given author published in the same year is used, differentiate by adding an identifying letter to each date to avoid confusion. The letters also appear in the reference list, where the works are alphabetized by title.
For example:  (Smith, 1997a); (Smith, 1997b)
 
If the author of the source is unknown, a shortened version of the title is used in the text to identify the work.  The title of a book is underlined; the title of an article appears in quotation marks.
For example:  (Surprising Solution, 1988, p. 8); (“Surprising Solution,” 1988, p. 8).
2.  References
(The format is correct for the following examples but the spacing and indentations may be incorrect!  The list should ALWAYS be double spaced throughout and the first line should be indented (like a paragraph).)
The list should be double-spaced throughout, each entry using paragraph indentation (the first line of each entry indented five spaces and the following lines at the left margin). A typical entry consists of four elements, each ending with a period:  the author’s last name and initials, the publication date in parentheses, title, and facts of publication. The following is a sample of typical entries.
