You cannot forbid books because there is no practical way to
know that book are not used without the source code.

The only thing that you can do is to limit the
size of the book together with the program
because finding how much memory the program use
is easy.

I think that books are not very important and
when you have many initial positions wasting time
about building books is not going to give much
unless the time control is blitz.
