Online Citation Style Guides: Links to sites with guides for Chicago, APA and Turabian style citations.
MSU Libraries also has a complete collection of the major citation manuals in print.
Citation management tools allow you to create, manage, organize and share personal and/or group collections of citations and references. They will also automatically format references and bibliographies.
