You probably remember the days when Gene Trimble did research & write-ups on various illegal clubs around the country. He would mention a special "friend of the hobby" source of research that seemed to be able to look up all kinds of obscure things, including the use of old newspaper morgues, etc.

I wonder what the "friend" could do today with ChatGTP helping out!

I never did hear the name of the "friend" though Ed H. and others would know.
