Someone must have built the very first part of the Clockwork Book because things like the Book don't just happen. They're always somebody's idea. But because the Clockwork Book is... well, clockwork, it has many moving parts. Quite a few of those parts support the Book by rolling out new pages, expanding its massive cover, and, in short, Making More Book.

The Book is much more, today, than it could have been on the day its gears began to turn. As a result it really doesn't matter who created the Book, or why; we suppose that the Book knows, but in order to find out you would need to ask the Book. Which is exactly the kind of thing that most people are too smart to do.
