CiteULike

This is a short endorsement of a great web-based tool named CiteULike. It was created and is run by Richard Cameron, of Manchester Metropolitan University's Department of Computing & Mathematics. It is basically an online database for storing citations. As the citations can be exported to BibTex and Endnote-Format it can replace storing everything in your citation manager. The killer-app-advantage is a function that allows you to post an article from JSTOR or similar databases directly to your citation database. This is done via a bookmark in your browser... So it's basically a one click functionality - in my eyes superior to all citation import functions offered by the journal databases. Another feature is that you can browse other user's libraries so it can be quite useful for drawing on other peoples collection efforts to find articles related to a certain field. Here is my library. The registration and usage are extremly straightforward.... Great Tool !
