For anyone who is interested in golf course architecture, this book is a must for your library. Contains a complete index (a continuous work-in-process) of architects and their courses. Essentially every course in the world (including those which are no longer in existance), is listed including its location, date of orgin and the architects who created it also the provider of any known substantial (professional) renovation work. It must take a tremendous effort for the authors to keep this book up to date. I hope the fact that this book is no longer in print indicates that the authors are hard at work. If you do not have a copy find one, if you have to go the the library and photocopy theirs (but bring a stack of dimes its very long).
