I've mentioned the CiteTrack Feature before: "CiteTrack will alert you by email whenever new content in a participating journal is published that matches criteria based on the topics, authors and articles you want to track. The list of participating journals is quite long, and this service remains free. This is obviously a good deal, as we get a very similar service as that offered by Medsite for a fee. Medsite remains a bit of a klunky site, with medbookstore being the most prominent (and well designed) component. Nonetheless .. they are agressive folks, and they are working very hard on displacing Medscape from the #1 Medical portal position.
