Has anyone worked with ISBN numbers yet? Specifically, the two different formats (the old one, and the new 13 digit format) and how a single book can have two ISBN's.
I'm doing a book tracking app, and I don't know a convenient way to handle a book that has both ISBN's. I'm leaning toward writing a library that will convert them to the 13 digit version, then just work with that, but it would be more work than I'd like.
