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, social media posts, dissertations, and more. With this focus on source evaluation as the cornerstone of citation, MLA style promotes the skills of information and digital literacy so crucial today.
