Oh, I have library books due today! This is a pretty darn useful service, since keeping up with the library book due dates is not that easy (did you know that they no longer stamp the due dates on the inside of the covers???). Not to mention it reminds me of what books I have on hold.

They deliver notices via email or RSS feed (or both!)

How does it work? The website doesn't say much, but I'd guess they use your login to the library site to scrape the account status page into their DB, which they then use to generate emals and rss feeds. They actually do a real time check when you click through the rss reed link. (It seems to be an asp/.Net application.)

How do they make money? I'm guessing the amazon affiliate linked recommendation on the right side of the email/webpage. They have pretty good data to do this with, so maybe it will work out to a reasonable income stream for them.

Business Idea/Feature for them or someone else: Tie your Amazon wishlist into your local library to request/put holds on your wishlist books, one or two at a time. (This is basically what I do manually.)

So, if you use your public library, go check it out.
