With groups, you collaborate remotely with project members, set up web-based bibliographies for classes you teach, and so much more.
Zotero is a free, easy-to-use tool to help you collect, organize, cite, and share your research sources. It lives right where you do your work—in the web browser itself
Of the different ways to automatically generate bibliographies (as well as in-text citations and footnotes), the easy-to-use word processor plugins are probably the most flexible. These plugins, available for Microsoft Word and LibreOffice/OpenOffice/NeoOffice, create dynamic bibliographies: insert a new in-text citation in your manuscript, and the bibliography will be automatically updated to include the cited item. Correct the title of an item in your Zotero library and with a click of a button the change will be incorporated in your texts.
To get started with these plugins, check out the following links. You can also get a taste of how these plugins work in action by watching screencasts of Zotero and Word or of Zotero and OpenOffice (by Daniel de Byl).
