On the Macintosh there is a program called Delicious Library that lets you use your iSight web cam to read in the bar codes. It then looks up the product at Amazon and stores it in your "library." You could scan in all your books (and movies and CD's) and sort them by Author or my Title to see which you like best. Then file them accordingly. It gets the book cover off the web too and gives you a virtual book shelf. The software also lets you check-out the book and track that activity. http://www.delicious-monster.com/ This program pretty much rules.
