The Kroch Library at Cornell (turns out it's pronounced "krock" and not "crotch") has exhibits from the Walker Library of The History of Human Imagination. Which is to say some rich guy's private collection of cool stuff. I wentt there with a friend and saw stuff including a Sputnik satellite. We also got a tour of an archivist's selections from Cornell's Rare and Manuscript Collection (including a copy of The Gettysburg address and a page from a Guttenburg bible, but I didn't take any photos there--I assumed they're not permitted).
