Here are a variety of resources that will help you with citing sources. The citation format that you use in your research paper will depend on what is required by your professor. Be sure you know the requirements before you begin.
With these tools you can collect book and article citations from the library catalog and databases. Then using a plugin for MS Word, you can insert those citations into your paper in the appropriate format.
See the library guide, Manage Citations with Zotero, Mendeley, and EndNote, on how to use these tools.
