Is there a good Pete Dye biography I'm unaware of? If not, that seems like an obvious one.
Honestly, I really liked "The Golf Courses of Seth Raynor" and would love a book in this style about several other architects. A high level summary about each course, how it came to be, what changes have been made, and key features that makes it stand out. All with great pictures. A book like this would be enjoyable for MacKenzie, Ross (too many courses, so maybe pick the top 100?), Bendelow, Flynn, Morris, Maxwell, Macon, Dye, Tillinghast, Langford, Thompson.
