Query: Disappointing

I picked up this book as a brand new Judo student looking for tips and techniques, and I was very disappointed. This book goes over only 3 throws, 3 chokes, and 1 pin technique. There are no escapes, no counters, and no reversals. There is some okay general information on Judo history, competition, refereeing, etc, but I need to learn the basics before I worry about how to be a referee.
