CiteUlike

CiteULike "CiteULike is a free service to help academics to share, store, and organise the academic papers they are reading. When you see a paper on the web that interests you, you can click one button and have it added to your personal library. CiteULike automatically extracts the citation details, so there's no need to type them in yourself. It all works from within your web browser. There's no need to install any special software." This is neat - particularly for academic librarians, who might appreciate being told about this..When visiting certain supported sites (see list at http://www.citeulike.org/post), CiteUlike automatically extracts citation details. For sites that are not supported, you can type in the citation information manually. This is a nice way to build your personal library of "to read" items on the web.
