Although I'm a new member, I thought I'd share another one:
While not a book specifically devoted to architecture, Driving the Green by John Strawn is a very interesting read about the making of a course in West Palm Beach called Ironhorse. The author was an associate of Arthur Hills at the time (not sure if he still is), and he chronicled the entire process of making the course, from the original idea and vision of the developer to finished product. It is more a tale of the trials and tribulations associated with the whole process than an analysis of course architecture, but it is well worth the read for anyone interested in architecture and, especially, course development.
Please note that this book recommendation is in no way a comment on Arthur Hills and his design philosphies/principles (or lack thereof?).
