I love a good club / course history. 1,600 books on just that topic is an impressive collection, well done Michael!
A couple more that I think are quite excellent and not mentioned:
Bel-Air Country Club, A Living Legend (~1993). Very nice, not too dense with a good synopsis on history of both the course and the club. Of course, it could use an update given the recent restoration.
Mount Bruno Country Club (2018). Published in conjunction with the club's centennial celebrations. Excellent early history on the WPJ course and club with detail on the changes to the course throughout the years.
Boston Golf Club (~2019). Not often do you get a club history published within 15 years of a club's founding. As a result, this is an extremely interesting book filled with rich detail on the founding of the club, site selection, architect selection process, iteration on the routing (including multiple alternative routing maps), and construction. A great memorial to John Mineck.
