Zotero is an easy to use citation management plug-in only for PC and Macintosh versions of Firefox. It stores citations in Firefox, runs whenever your browser is running and allows you to import citations by clicking on an icon in your browser address bar that appears automatically whenever a web page contains citations. Zotero works with all major catalogs and databases, and is a free, open source product. Recently Zotero.org launched a service by which you can create an account to synchronize your citation library across multiple computers.
