I have recently started using Connotea which is what they now describe as ” Free online reference management for clinicians and scientists”. I remember seeing a presentation on Connotea at the Data webs workshop I attended, (excellent day of talks and discussions), where Connotea was described as a “social bookmarking for scientists”. I wasn’t overly convinced to use it then and my initial perception was that it was del.icio.us for scientists, so why not use del.icio.us? On a more recent, closer look, I see they have re-branded (or re-advertised) and are concentrating on tagging publications and providing exports to various reference managers, particularly bibtex, my favourite. This feature has convinced me to give it a try and as I am writting my thesis at the moment and I am really putting it through its paces.
I am liking it so far and definately “Discovering” new resources based on my tags. Hopefully I will never need to ask the questions again “Where did I put that paper?” or “I knew I read a paper about ontologies but which one was it?”
