Parenthesize the editor's last name and publication date, and insert it at the end of a relevant sentence. For example, if you've just paraphrased a statistic from the book, end the sentence with "(Editor's last name, 1999)."
Write the editor's full name in your Works Cited page. The last name should appear before the first name, and parentheses should identify the person as the editor. Yours should resemble this: "Doe, John. (Ed.)." If there is more than one editor, include the relevant names in alphabetical order: "Doe, John & Smith, Jane. (Eds.)."
Follow with the parenthesized date of publication and the title of the book. The next part of the citation should look like this: "(2003). Student's guide to APA formatting." Under APA format, the title of the book need not be in title-case.
Conclude the citation with the location of publishing and publisher: "New York: Random House."
