Thursday March 28, 1968. I’m working away at my job in the documents acquisitions section of the Columbia University Libraries. My phone rings. Tom. “I’ve just got 2 tickets to an invitational screening of “2001, A Space Odyssey” at 1 o’clock this afternoon. Can you get off?” I hollered out to my boss, and when he heard the news he immediately said yes. I hopped on the subway and headed to Times Square, grabbing a hot dog somewhere along the way.
