A Rose by any other Name wrote: I believe that things happen because they are written in the book. That the book is a precursor, that perhaps dictates what happens. My other theory is that what we are watching isn't actually happening its just a bedtime story being told to a child out of said book. That would make a very creepy bedtime story to tell a child.

With this said, I don't think there are other books. As far as we know now, the OUAT book was written simply because somebody had to believe and lead the Saviour to believe, too. It was specifically about FTL and touched other realms only when FTL people were involved (Wonderland and the Mad Hatter). I strongly doubt it has any mystical property – or any property at all beside that. Not all the stories seem to be in there (otherwise Regina first and the Charmings then would have known the reason why Rumple created the curse, and even about Rumple's prophecy), and one tale was even added right before the Curse was broken (Pinocchio), yet it clearly happened before. I think the book simply chronicles some of the events occourred in FTL, and none exist for other realms because there was no need of them.
