If you have not seen it already, UCSD has put a lot of reviews of classic works on Chinese history on-line. They look to me like the type of things grad students in a reading circle for their comps would be passing around, which makes them handy if you are studying for yours or if you just want to know more about Chinese history. They are more useful that reviews from journals, particularly for the older books, as they tend to try and figure how how valuable some of these things are given developments in scholarship since they were written.
