BioMed Central Integrates With CiteULike

From BioMed Central's Update:

"CiteULike is a free web site that allows you to keep track of your favourite articles, tag them with keywords, and share them with others. A key feature that makes CiteULike easy to use is that it provides a button to add to your web browser. When you click on that button, when viewing any article on a website supported by CiteULike, the bibliographic details for the article concerned will be automatically retrieved and added to your CiteULike library.

CiteULike now supports all 150+ BioMed Central journals, making it easy to add BioMed Central articles with a single click. What's more, the latest articles from all BioMed Central journals are now listed on the CiteULike electronic table of contents page."

A similar site is Connotea, from Nature Publishing Group: www.connotea.org.

Features of both sites include:
- The list of tags/keywords on the home page shows large and small tags; the larger ones are used more often
- You can see other accounts who have saved the same articles as you; you can also see what other tags have been used for that article
- If there is an article in another account that interests you, you can add it to your account as well.
