In the Works Cited entry, list both authors in the order they appear on the source
Write the first author’s last name, first name, then the second author’s first name, last name
Example: Smith, John, and Jane Doe
In an in-text citation, include both last names
Example: (Smith and Doe 23)
If the source has three or more authors, use the first author’s last name followed by et al. in the in-text citation
Example: (Smith et al. 23)
