Query: Excellent Book for Learning Golf

This book is very different from many books on learning the golf swing, but it is the basis for many of the current, more modern approaches to instruction. I have found it to be fascinating to read and practice. Never has it been so easy to automatically get 'in the slot' using this approach. He never even mentions it, not only because the language was different when this was written and 'the slot' wasn't a term yet, but because it's automatic if you swing as he instructs you to. This is a must read!
