Best I can tell there are 19 Cowdog books missing from the collection. None of them are on the ready for checkout list and none of them are on the books in process list being worked on. They are also not on the awaiting approval list or on the being scanned list, although I think that does not currently include outsourced books. And I couldn't find them on the wishlist either.
