APA 6th Edition

According to the American Psychological Association (2010), when formatting the title information for a nonperiodical (e.g., books and reports):

Enclose additional information given on the publication for its identification and retrieval (e.g., edition, report number, volume number) in parentheses immediately after the title. Do not use a period between the title and the parenthetical information; do not italicize the parenthetical information. (p. 185)

The APA manual provides a couple of examples on page 205 of references to specific editions of resources (see examples 28 and 30); however, please see below for a sample reference, as well as the edition noted in the reference to the APA manual below.

Kouzes, J., & Posner, B. (2012). The leadership challenge (5th ed.). San Francisco, CA: Jossey-Bass.

APA 7th Edition

When presenting titles of books or reference works in references,

enclose edition information, report numbers, and volume numbers in parentheses after the title. Do not add a period between the title and the parenthetical information. Do not italicize the parenthetical information. If both edition and volume information are included, separate these elements with a comma, placing the edition number first. (American Psychological Association, n.d., Format of the Title section)
