EndNote. RefWorks. CiteULike. Zotero. Biblioscape. WikIndx. Who can keep it all straight? A new Wikipedia entry takes a stab at this! The article on comparison of citation management tools lays out the current landscape on these tools very well including commercial, free, and open-source, desktop-based, server-based and web-based tools. It includes charts on how they stack up on integration with word processors, supported platforms, import and export capabilities, citation styles and more. Very useful!
