I cannot post this in the reading room so I'm asking it here.
In your opinion, what are the top 3 best books about golf?
Depends on what aspect of golf you are talking about. Instruction? History? Personalities?
Narrow down what you are asking.
My favorite two are Bob Hope's Confessions of a Hooker - My Life Long Love Affair with Golf
and the book about Titanic Thompson's golf hustling career - The Unsinkable Titanic Thompson
according to Bob Hope, the only reason he got into acting and the entertainment business was to support his golf habit.
These provide a great insight into pretty much everything one needs to know about how to play the game, how the modern game evolved and beginnings of professional golf, and what golf course architecture is all about.
