Doubtful. A robust protocol would be to scan several of each edition (to ensure no scanning errors), and scan each edition. Then too, these books are being purchased in lots with accidental duplicates, and all the major labs are doing it. So we're likely talking about tens of each book. For rare books - anything over a couple of hundred years old or small print runs either, that could well be most or even all copies. This wouldn't be immediately noticed either, especially if the books aren't currently considered noteworthy or well known.
