Zotero Citation Management Software
Zotero provides a way to organize and store citation information about the books, articles, and other materials you find through your research. You create your own personalized library than can also store PDFs and can be backed up to a cloud server. When it comes time to generate a works cited page or bibliography, these tools integrate into Microsoft Word to generate a Works Cited page in seconds (of course you will need to double-check what is generated).
Citation management tools like Zotero or Endnote can be a big help to your organization and time management, especially for larger projects. Zotero can also help facilitate group projects if you are working with collaborators who would like to set up a group library.
