I recently picked up the 2010 edition of the above referenced book and have thoroughly enjoyed every page so far although not yet finished. There is a star studded list of GCA types as contributors including Ran, Ben Cowan-Dewar, Mark Rowlinson,Tom Doak,Mike Clayton, Dan Wexler, Rich Goodale, and Ulrich Mayring. There is something for everyone from the great courses themselves by region to an introduction that discusses the different eras , the architects, routing and design, greens and bunkers etc. Plenty is packed into 320 pages including text, photos and diagrams. As a reference guide and an introduction to understanding the origins of golf this book is fantastic. What say those that own a copy?
