The 8th edition of the MLA Handbook is now available. The new style guidelines for the works-cited list have been simplified. It's no longer necessary to consider the publication format of the work being cited. Instead, create an entry using MLA's list of core elements, in the order specified.

Manage your citations with RefWorks, a tool that allows researchers to easily import, export, search, and create automatically formatted bibliographies online. Citations found via searches in library databases such as JSTOR and many other databases can be imported directly into RefWorks. No manual typing required. Bibliographies generated within RefWorks can then be exported to Word in virtually any citation format, e.g. MLA, APA, Chicago, Turabian and others.
