In the new edition, the MLA recommends one universal set of guidelines, which writers can apply to any type of source. Shorter and redesigned for easy use, the eighth edition of the MLA Handbook guides writers through the principles behind evaluating sources for their research. It then shows them how to cite sources in their writing and create useful entries for the works-cited list.
This site from Trinity College presents visual information about how to cite various sources in a visual way, and they offer guidance on citing tricky sources. Check out the source help for APA, Chicago, and MLA styles.
