I'm not sure if Ian had intended this thread to go in this direction, but all the participants seem to be dancing around a central issue without coming out and saying it. That it is unclear as to whether or not architectural societies can or do exist to endorse the restoration work of one architect over the next.
As a member of the Tillinghast Association, I feel the groups sole purpose is to amass and report upon the ideas, theories and architecture of A.W. Tillinghast.
The website seems to corroborate my ideas with this mission statement:
To share with fellow golfers A.W. Tillinghast's historical perspective and vision on Golf, the greatest game.
The Tillinghast Association was founded in 1998. Its primary goals are to share the accumulated research and knowledge on A.W. Tillinghast -- his fascinating life, his remarkable golf courses, his charismatic and humourous writings, and his foundation principles to Modern Golf Course design and construction.
Now, as Tom correctly pointed out with my first post on this thread, anyone could use their position within an architectural society to curry favor for restoration work if they so desired and I can probably think of a few people who have, myself included.
I just don't see how that is necessarily a conflict of interest. None of these societies exist to EXCLUDE information from interested parties. The Donald Ross Society has posted restoration guidelines on both their homepage and Golf Club Atlas and they are freely accessed by anybody who wants them.
I've used information from the Tillinghast and Ross Societies websites to help with my master plan from the Penn State White Course done by Willie Park, Jr. I've cited my membership in the Tillinghast Association as a resume point to Penn State and prospective employers to show my dedication to certain traditions within the game. All told, this is being used to indicate my personality and passion, and not to leverage my own knowledge over someone elses. My own work and knowledge will speak for itself and if a prospective client or employer interperets that differently, they aren't doing their homework.
In the end, this still boils down to the ego and ethics of the individual.
