I can't think of much i've run into that would be more helpful. Let me know what your results are! I need to deal with some 8500 books arround september.
Once you do figure it out, get yourself a bar code reader. extra credit . The cue cat from radio shak would be nice to support (its free) but I didn't have any luck figuring out how to decode what's coming off the device. others seem to have better luck. If you plug it into a linux box and scan some barcode, it spits out garbel i couldn't for the life of me decode.
Best of luck.
