Zotero [zoh-TAIR-oh] is a free, easy-to-use web browser extension to help you collect, manage, and cite your research sources. It has been developed by the Center for History and New Media (CHNM) at George Mason University http://chnm.gmu.edu and is now in use by thousands of historians, anthropologists, journalists, lawyers and other researchers.
Zotero is an open source alternative to citation tools like Endnote, and lives inside of your browser, allowing you to automatically capture and manage sources and citations in online catalogues, archives, and other repositories, as well as taking notes, tagging these materials, and exporting bibliographies in various formats. For more information and to download and install Zotero, go to http://www.zotero.org
Zotero requires use of Firefox 2.0, the latest version of the popular open source web browser from the Mozilla Corporation. If you don't already use Firefox or haven't yet upgraded to the new version 2.0, go to http://www.getfirefox.com to download it. Once you've installed it or upgraded your earlier version, go to the Zotero site to download and install the extension for Firefox 2.0.
Best,
