The Tri-College Libraries recommend Zotero, a free online app that can format your bibliography, keep your citations organized, and even save your articles in the cloud so you can access them later from the library, home, or a café.
A Tri-college guide to installing and using Zotero to save your references and then cite them in footnotes and the computer-generated bibliography.
See Zotero in action with librarian Brie Gettleson. Walk through important processes including creating folders, saving citations from the Tripod catalog and other sites, tagging saved journal articles by keywords, and creating bibliographies and footnotes.
