Actually, if you allow for 9 characters not just limiting it to 0-9 you have 0-9 and A-Z maybe skipping O and I to not confused them with 0 (Zero) and 1 (One). This would give you a heck of alot more than 1billion codes. So, you could even make it a bit shorter and still allow for alot of books. (Perhaps someone that is better at math than I am can figure how many that would allow. I always forget how to figure this out.)
But, I like your idea... the root of the ISBN would be for the content then a few extra digits for language, format, publisher, whatever.
Then search engines could easily adjust to show you not just the format you searched for if you look for the full ISBN but for all the formats of the same book.
