What Zotero Does
Zotero (pronounced "zoh-TAIR-oh") is a free, open source citation management tool that that helps your collect, manage, and cite your research sources. It's easy to use, and is completely free. Zotero allows you to attach PDFs, notes and images to your citations, organize them into collections for different projects, and create bibliographies. It automatically updates itself periodically to work with new online sources and new bibliographic styles.
