MLA citations style consists of a works cited list and use of in-text citations. Use this guide as a reference point on how to cite correctly.
When using more than one author, use this as a guide:
With two authors, or coauthors, add both names to the in-text citation, with the word
and between the two names.
(Dorris and Erdrich 23)
With three or more authors, use the first author's last name, followed by et al.
(Burdick et al. 42)
