What are Citation Tools?

Citation tools offer an easy way to collect and manage references, research notes, and PDFs. They can also generate in-text citations and bibliographies. These are the four major tools (Zotero, Endnote, RefWorks, and Mendeley). Many historians use Zotero, but you should choose whatever works best for your needs.
