This seems tricky to me--if the barcode is the ISBN, then you can never have multiple copies of the same book (because barcodes must be unique).
If you will really never have multiple copies of an item
In addition to this, be aware that duplicate ISBNs are a very real thing, even though it shouldn't be possible. e.g.: http://www.abebooks.com/9780943161853/Walter-Breens-Encyclopedia-Early-Unite... http://www.abebooks.co.uk/book-search/isbn/9780943161853/page-1/ -- Robin Sheat Catalyst IT Ltd. ✆ +64 4 803 2204 GPG: 5FA7 4B49 1E4D CAA4 4C38 8505 77F5 B724 F871 3BDF
