I recently stumbled over these absolutely stunning photographs of (usually deserted) libraries.
I have no idea what it is about libraries that fascinates me so much. I remember when I wanted a copy of the paper about injecting an elephant with LSD that I had to go into the mysterious locked basement of Nottingham University library. It was wonderful! there were these massive old journals. One in particular, "Transactions of the Royal Philosophical Society (1830)" just looked and felt so fragile. There was something just thrilling about reading the words (and being terrified of even touching the paper in case it ripped).
Even after finding the paper I wanted, I spent quarter of an hour just wandering around, all alone, in a massive deserted basement with only the scribbled thoughts of a million dead men to keep me company.
