It varies by publisher--for example, in my experience, Harlequin (a
publisher of romance novels) seems to have used all of its ISBNs *at
least* twice. It's a real problem, if you expect an ISBN to be a
unique ID for a book, and worse if you wanted to it be unique to
edition or so on. Well, it's a minor issue from out point of view, I
guess. How would Mediawiki scale to 130 million articles? Gotta cover
everything...
