By Kim Sol, 4^th Dan Judo, University of Montana Daigaku Judo Dojo. These are my impressions of Judo books available.

Judo has produced a martial art literature, spanning over a century, unequaled in its breadth of styles, approaches, philosophies and techniques.

 Judo books comprise a remarkable body of literature describing a complex interface of human combat experience and movement art. It is always worth browsing used bookstores for out-of-print Judo books. One of the best internet engines for used book searches is Bookfinder.com
