Patrick:
Dr. Klein's book on Ross is excellent. For a lighter read, consider "Rough Meditations" by the same author.
"Driving the Green" by Strawn is in my library but I've only skimmed it. He writes about the project to build a South Florida course (Ironhorse?). Not as much about design as the modern field of golf architecture.
I like books about golf courses. If those are included in what you are looking for I'll add "Golf Courses of the MGA" - a way for me to live vicariously as one of the fortunate that gets to play all the New York area private clubs.
"Missing Links" by Wexler is awesome. Love it.
Many of the books about architecture are less interesting to me than the pictures. Not that you've ever done it Ave Maria boy, but imagine someone reading the interview about turn-ons and turn-offs before looking at the centerfold!
Did he just say that? This website is named for Ran's favorite golf book as a child, one I too pored over forever.
