APA Style Guide: Date

American Psychological Association rules for formatting papers, in-text citations, and end references. Examples based on the sixth edition of the Publication Manual from the APA. By Alexis Carlson

Date

Books (6.28)

The date follows the author's name and is enclosed in parentheses and a period after the last parenthesis. For books, give the year. You find most publication information inside the book on the reverse of the title page. Look for the © symbol to find the year. Give the most recent year listed.

Example:

Coleman, S. C. (2005).

Journals, Newspapers, & Magazines

Journals often contain a month and year of publication. Give only the year in the following format (Year).

Example:

Wade, K. L. & Tillman, B. (2009).

Most newspapers and magazines list a day as well as a month and year. Give all the information listed in the following format (Year, Month Day). Always spell out the month name.

Example:

Schulyer, T. (1993, September 2).

If a season or more than one month is given, treat these as you would a single month.

Example:

Riley, H. J. (2011, Fall).

Harris, C., Hall, A., & Cicero, H. D. (2004, July-August).

No date

Items without any date listed are most commonly websites, but use n.d. (for no date) for any item that does not have a publication date listed.

Example:

Johnson, K. L. (n.d.).
