I really like Judo unleashed by Neil Ohlenkamp
The book is in color and has close ups and step by step including a foot chart where your feet are suppose to be entering for a throw and throwing. The book breaks techniques into catagories such as Fundamentals, Shime etc etc. The book gives the English meaning of the Japanese technique and also adds some additional information about the technique such as who used this technqiue or which was one of Kano's favorite throws.
Kodokan Judo is a great one. Another favorite is "Judo and Aikido" by Kenji Tomiki. The first 60 pages or so contain a great discussion on posture, walking, balance, etc. Not so much a discussion for the sport player but more for the martial artist/self defense. Good stuff. The problem with this book is it is long out of print and copies found on ebay are expensive.
I have been interested in the "Cannons of Judo" but due to the high cost of this out of print book I haven't purchased it just yet.
I have Sensei Ohlenkamp's book, very well done.
he runs judoforum.com a great website.
I also like Drager and Ishikawa'a
Judo:Training Methods and Judo: Formal Techniques.
