LibraryStories uses a RSS-ish feed called ATOM which enables people to "subscribe" to updates instantly on their machine. But I want you to think about RSS technology outside the blog arena and think about it for the library catalog. Many libraries have "new book" lists that their catalogs automatically do--but what if you had an RSS feed for you library catalog?
While Web publishers slept | Perspectives | CNET News.com:

"Just about every major online news source uses RSS to deliver content to subscribers. RSS has been adopted by major publishers such as CNET, the BBC, Yahoo, Motley Fool, InfoWorld, The New York Times, the Christian Science Monitor, Wired News, The Wall Street Journal and many others, including a rapidly growing number of local and regional newspapers.
Unfortunately, most of these media companies do not yet understand the impact that RSS is having on their Web site traffic, also known as the 'RSS Effect.' They know even less about how to monetize this new content channel.
Moreover, they don't know who's using it, when and how. And most important, they don't know how much traffic and revenue their Web properties will forgo as a result. To publishers, the whole issue of RSS is not a question of 'if' but of 'when.' "

A good read and some warnings to publishers could be taken to heart by libraries.
