There are many types of barcodes. The ones you see on food items are usually UPC-E or UPC-A
here's a site that shows quite a few code types: http://dynamicstatements.com/barcodes.aspx
Code 3 of 9 is also knows as code 39 (shortened name) the reason I mentioned this one is that
you can encode text as well as numbers. The problem with it is that it grows laterally as the number
of characters increases making it sometimes hard for the reader to capture.
Probably best to use ISBN code for book id which is all numeric, and uses Bookland EAN, or EAN-13
codes.
There is a group that is building a database for every product ever made, including books, and it's free
you can find out about it here: https://product.okfn.org/
and see some of their work here: http://product-open-data.com/
This is a good place to start learning about what's available.
