CiteULike

Springer has a new service which is rather interesting, called CiteULike, which can be found at citeulike.org. It allows one to easily (the keyword here, using just a few clicks) create an online database of articles they find online. The interesting thing about it is that it also allows other people to have access to your online library through the formation of groups. The libraries of individuals within the group form a shared library accessible to anyone in the group. Groups are easy to set up and can be set as either open for anyone to join or restricted so that people have to apply for membership. Few groups right now have many people, but as more people use the cite, the more useful it will be.
