Hi David,
Sorry for giving wrong information about the 19x19 book in Many Faces. I
thought you use a book only on 9x9, but you also use it on 19x19 to bias the
search, which looks a good idea to me.

On 19x19, Many Faces has books. A full board opening book made from strong
player games is a hash of all positions (rotation/refection invariant). It
keeps statistics of player strength and win rate, and is only used to bias
the search, not to choose a move quickly.
It also has a joseki book with all published lines in english, entered from
books (about 60K positions).
On 9x9 I have a full board book made from strong cgos games, but I don't
ship it with the program.
David
