The MLA Handbook, formerly the MLA Handbook for Writers of Research Papers (1977–2009), now in its eighth edition, is a publication of the Modern Language Association (MLA). According to the MLA, the MLA style "has been widely adopted for classroom instruction and used worldwide by scholars, journal publishers, and academic and commercial presses."
Like the MLA Style Manual, the MLA Handbook is an academic style guide widely used in the United States, Canada, and other countries, providing guidelines for writing and documentation of research in the humanities, such as English studies(including the English language, writing, and literature written in English); the study of other modern languages and literatures, including comparative literature; literary criticism; media studies; cultural studies; and related disciplines. Released in April 2016, the eighth edition of the MLA Handbook (like its previous editions) is addressed primarily to secondary-school and undergraduate college and university teachers and students.
Kate L. Turabian's Manual for Writers of Research Papers, Theses, and Dissertations presents two basic documentation systems: notes-bibliography style (or simply bibliography style) and author-date style (sometimes called reference list style). These styles are essentially the same as those presented in The Chicago Manual of Style, seventeenth edition, with slight modifications for the needs of student writers.
Bibliography style is used widely in literature, history, and the arts. This style presents bibliographic information in footnotes or endnotes and, usually, a bibliography.
The more concise author-date style has long been used in the physical, natural, and social sciences. In this system, sources are briefly cited in parentheses in the text by author's last name and date of publication. The parenthetical citations are amplified in a list of references, where full bibliographic information is provided.
Aside from the use of notes versus parenthetical references in the text, the two systems share a similar style. Click on the tabs below to see some common examples of materials cited in each style. For a more detailed description of the styles and numerous specific examples, see chapters 16 and 17 of the 8th edition of Turabian for bibliography style and chapters 18 and 19 for author-date style. If you are uncertain which style to use in a paper, consult your instructor.
