Query: A Good Reference Book

This is a good reference book to have in your library. It is essentially a dictionary that has about four different sections. The most interesting section lists every discipline imaginable and provides brief information on each. However, there is alot of info that may be of not much interest (what an Axe Kick, Front Kick, Roundhouse is.) It may be of particular interest to those that practice and/or are interested in most stand-up fighting disciplines (Kung Fu, TKD, JKD, etc.) Not a must but nice to own.
