Copy editing: ask the audience!

The paperback versions of volumes 2 and 3 of The History of Philosophy Without Any Gaps book series are on the way! So we're talking here about Philosophy in the Hellenistic and Roman Worlds; and in the Islamic World. I am allowed to make small corrections - not adding whole chapters or whatever but I can fix little things. I'd be grateful to know if anyone has spotted typos or factual errors in either book.
