The Ebling Health Sciences Library at the University of Wisconsin offers a list of medical and science journals that have RSS feeds. The list of titles with RSS feeds. The library subscribes to the feeds and presents the most recent table of contents on the screen. Each article is linked through the library's proxy server to the full text content available to library patrons. And, of course, there's a link to the actual RSS feed from the publisher. (This publisher-provided feed, of course, does not link through the library's proxy server.)

Presumably, with a big more data massaging, the RSS feed could direct patrons through an OpenURL link resolver to the most appropriate source of the journal (online, interlibrary loan, etc.).
