So you love citation management services - RefWorks, EndNote, Zotero, Papers (for the mac) etc. You love the ease of adding the citations of articles you find to your very own account. You love generating bibliography lists with a few quick clicks. You love how it keeps your citations findable forever. But if you have compared the available services, what makes one of them really stand out from the others?
If you refer to arXiv very often and need to download citations, you might want to consider Zotero, a free, easy-to-use Firefox extension to help you collect, manage, and cite your research sources. It lives right where you do your work—in the web browser itself.
