A friend at work put me on to this really cool downloadable software called Library Books. (Here's a write-up and here's where you can download.) It's a little program that automatically links to your library's catalog and retrieves your account info (what you have checked out and when it's due). It's so cool! And really unobtrusive. Here's a screenshot of my desktop's right upper-hand corner. See the little star and the 4? That means I have 4 books checked out.
Then if you click on the star, a little menu drops down listing all your books and when they're due. The icon apparently turns red when you have items overdue.
And there are links to your library's webpage too.
I may never have to pay fines again. Mom, you might even be able to start using the library again! Or have they banned you for life? ;)
Oh, this program is for Macs only. But apparently there is something called Library Elf for PCs.
