My birthday is coming up and wanted to give my wife some ideas. I was in the book store today and went to the golf section to get an idea of what I might want.  I was wondering if anyone had any input on which golf book(s) to ask for. If you could give me a few ideas I'd appreciate it. I'm leaning towards history and legends of the game but books on the mental aspect and instructional books would be nice too. I have a few in mind but need some help. Basically, give me your must have golf books list.  Thanks in advance.
