Keeping Track of His Collection

If you think barcode scanners are used only for businesses, then your missing something.  When hubs almost gave up organizing and making lists of his movie and music collection, we thought of using his spare usb barcode scanner that was just collecting dust in the attic.  He has a lot more of these CDs that were borrowed and he lost track of them.  Now he can track who borrows what.  I'm also thinking of using it with my books.
