BibSonomy – A Blue Social Bookmark and Publication Sharing System
http://www.bibsonomy.org/

BibSonomy is a system for sharing bookmarks and lists of literature. When discovering a bookmark or a publication on the web, you can store it on their server. You can add tags to your post to retrieve it more easily. This is very similar to the bookmarks/favorites that you store within your browser. The advantage of BibSonomy is that you can access your data from whereever you are. Furthermore, you can discover more bookmarks and publications from your friends and other people.
