The Modern Language Association (MLA) offers a style sheet and documentation format for writers. MLA is the preferred style sheet in many of the humanities, particularly English.
Students and scholars should follow the most recent edition of MLA and any unique requirements of a course of publication.
An excellent resource on-line for MLA can be found here:
