Pasi Keski-Nisula at the National Library of Health Sciences - Terkko (part of the University of Helsinki) was kind enough to let me know of a new service he has developed. FeedNavigator is a personalizable feed navigator for health sciences information.

In addition to aggregating (and providing search capabilities) for more than 1500 relevant RSS feeds, it also lets you save articles to your own space ("MyFeeds"). Citations for useful items useful to you can be exported to RefWorks. Users of the system who are patrons of several Finnish libraries can access full text through either an SFX (a common OpenURL link resolver) or document delivery service.

The service is free for use by anyone -- though a free user registration is required.
