English research paper...documentation?

I've used KniteCite for multiple papers in school. It was suggested by a writing teacher. Click the link. On the left column at the bottom, you'll find 'Online Only'. Select the type you want, put in all the information you have, and it will give you the correct documentation. You also have a choice of MLA, APA, and Chicago. Use the format your teacher wants. If your teacher doesn't specify a specific type, pick one type and use that for all of your documentation for the paper.
