Zotero [zoh-TAIR-oh] is a free, easy-to-use tool to help you collect, organize, cite, and share your research sources.
Zotero version 3 has just been released together with a standalone version. Formally only available as a Firefox Add-in the standalone version means you can use Zotero whatever your browser preference. To find out more about the standalone version visit this thread on the Zotero Forum.
WARNING: After many years happily using Office XP and Word 2002. I upgraded to Office 2010 and obviously Word 2010. Zotero installed ok and appeared in the Add-In tool-bar, however when I tried to insert a citation in my document I received an error message, see below. I searched the Forum for a solution without success. As I am in the middle of a dissertation I do not have the time to resolve the problem so I have reverted back to Word 2002, with which version 3 works fine.
