It is hard to take the engine's strength/weakness into account when build the book. some positions human can do great, but not computers. it is even possilbe that some class of positions one engine can do great but not another. On the other hand, human expert with deep knowledge, and have the access to the engine can really make some good book. 2. it is hard to keep up with the latest development in the openning theory. For my chinese chess program, more than half of the lost are directly from this. for chess this is better because the new games are put online pretty early, but it still a time comsuming and never end process, unless the book builder become automated. This is the weakest link in my chinese chess program. Because i am in US, away from most chinese experts, and my auto-generated is far from satisfy. Ren.
