yes there is! and it's wonderful... it's a website:
www.librarything.com
you can enter all your books online and even Tag them with reading levels or genres. then you can print out your list and use it to check which books have not made it back to your classroom library. i like it because you can also link your personal library page to your website and kids/parents can see what you have in your classroom library.
oh! and for $6 you can buy a little barcode scanner that will help you to enter all your books in. IT'S AMAZING!
