How to Cite Workbooks in APA Format

The sixth edition of the "Publication Manual of the American Psychological Association" offers format and style guidelines for the behavioral and social sciences. Procedures for both in-text and reference page citations are available for books, including workbooks. Rules vary slightly depending upon whether a book has authors or editors.

In-text Citation

When material from a workbook is included in the text of an essay, cite your source. Within parentheses, put the author's last name, a comma and the publication year, such as: (Doe, 2010). If there are two authors, separate their last names with an ampersand (&). If the workbook has an editor rather than an author, use the editor's last name in place of the author's within the parentheses.

Reference Page

If a workbook is cited in the text of an essay, it must be included on the reference page at the end. Begin with the author's last name, a comma, first name initials and a period. If there is more than one author, separate the names with commas and add an ampersand before the last name. Put the publication year inside parentheses after the author's name and add a period. Next, add the title in italics followed by a period. After publication title, include the publication location (including city and state), a colon, and then the publisher and a period. This is an example of a properly formatted citation:

Smith, A., & Jones, P. (2000). A Mathematics Workbook. New York, NY: The Math Company.

If an editor is identified for a workbook, the format is slightly different. Use the editor's name in place of the author's. Before the publication year, put "Ed." inside parentheses. Add a period. If there are multiple authors, format the names as you would for authors but use "Eds." in parentheses before the year. An example of a workbook with multiple editors:

Black, C., & White, T. (Eds.). (2003). The color handbook. New York, NY: The Art Factory.
