Zotero – See it. Save it. Sort it. Search it. Cite it.

Zotero [zoh-TAIR-oh] is a free, easy-to-use Firefox extension to help you collect, manage, and cite your research sources. It lives right where you do your work — in the web browser itself. Zotero’s idea of being a bibliographic manager that runs in your browser and grabs citations on your command from lists of books or journals is still appealing. Plus, the ability to make folders for your citations from particular topics is something that EndNote (via EndNoteWeb) is finally giving in to.
