I've had a hand in a few of these and collect them as well. It's usually the client, which is to say the club, that determines how much of anything, whether it's golf or non-golf sports or social events, are covered in a club history. I've had clubs that wanted a lot of golf course info and clubs that didn't want much of it at all. Happily all have been interested in their origins and the architecture can usually be covered there.
