American Psychological Association (APA): Multiple Authors

When a work has up to six authors, cite all the authors. When a work has more than six authors, list the first six authors, and use "et al." (not italicized and with a period after "al") to signify the remaining authors.


The entry should begin with the last name of the first author, followed by his or her initials. The date of publication comes next, in parentheses. The title should be italicized, but only the first word should be capitalized. The place of publication comes next, followed by a colon, then the publisher.

For more specific information, consult the Publication Manual of the American Psychological Association (Fifth Edition) or see the APA style website.
