Ok, sure! I've only been back twice since graduation but I'll do that if I'm still on ENWorld.
I envy you though. I loved exploring Alderman, something I never would have done had I not gotten that part-time job. Probably my favorite area was the old periodicals on the bottom floor. Amazing to take a book of magazines down and read about the writer's concerns about Napoleon III. Or for me reading the pre-war Japanese magazines with their anti-American jingoism. Never was allowed back to see Jefferson's letters or anything though. Something you probably have been able to do.
Speaking of Cthulhu and Alderman, I checked out the first Lovecraft I ever read from there as well. If I recall correctly the Lovecraft selection wasn't so good at the time.
