The Seattle Public Library is replacing its catalog with a system that offers RSS feeds. Keep track of your items out or keep on top of your favorite authors. Excellent. I’ve been considering putting together something like this for my Hennepin County Library account but have been too lazybusy. If I lived in Seattle, I wouldn’t have to! (via Digital Web)

Not sure where I learned this, but offers RSS for its catalog entries. Let’s say you’re keeping an eye on prices for Andy Hertzfeld’s new book, which has the URL Tack on “.xml” to that URL and you’ve got yourself an RSS feed.
