The newest editions (released in August) of the style manuals for both MLA (7th ed.) and APA (6th ed.) are now available On Reserve at the Reference Desk. If you'd like to see one of them, just ask a library staff member. They are filed under LIB001 on the Reserves shelf.
You can also access style and formatting guides on the new editions of the MLA and APA style manuals at the Purdue Online Writing Lab's Website: MLA and APA
