Authors

This section will cover how to format single, multiple, and no authors when citing in APA. For any other questions on how to format authors in APA, visit the APA Style page on Elements of reference list entries and scroll to Authors. 

One Author

For a single author, list the last name of the author, then the first and middle (if applicable) initial. A comma is placed after the author’s last name, and periods are included after each initial.

Two Authors

For two authors, list authors in order on the source by last name and initials, separated by a comma and the final name separated with an ampersand (&).

Three or More Authors

For three or more authors (up to twenty), list authors in order on the source by last name and initials, separated by commas and the final name separated with an ampersand (&).

If a source has more than twenty authors, first list the names of the first 19 authors. Then, use an ellipsis (…) in place of the final authors’ names. Finally, list the final author’s name (no ampersand needed).
