I'm trying to correct the information about the Art of Oddworld Inhabitants on Goodreads.com, but unfortunately my copies are both in a box, in a warehouse, near a dock somewhere. I'd like to know the ISBNs of the softcover, hardcover, and folio editions. If you've got one of the above, can you please go to your bookshelf and check?
Normally I'd check Amazon about this sort of thing, but this page says hardcover in one place and softcover in another.
