The library has many citation/publication style manuals in print, below are several sites we like for citation help.
Writing help is located in the Communication Center, on the first floor of the library. When you come by, they set aside one-on-one time to help you. You will be helped by your fellow students, and they even have subject specialists.
Called Citation Management Tools, these programs allow you to keep track of the sources you use, and when the time comes, generate the citations and bibliographies in the proper format (which you can select and change at any time!). Getting started with these tools is best done at the very beginning of a research project, but once you've added them to your workflow, you'll end up working smarter.
