Relied on by generations of writers, the MLA Handbook is the only official, authorized book on MLA format. The ninth edition builds on the MLA’s unique approach to documenting sources using a template of core elements—facts, common to most sources, like author, title, and publication date—that allows writers to cite any type of work, from books, e-books, and journal articles in databases to song lyrics, online images, YouTube videos, dissertations, and more. Emphasizing source evaluation as the cornerstone of citation, MLA style promotes the crucial skills of information and digital literacy.
