This video brings three thoughts to my mind:
1. Dang, how many librarians did Yale have back in the day?
2. Lots of boxes and heavy lifting. Not much has changed on the moving books front in the 78 (!) years since this footage was shot.
3. As someone who will soon be moving an entire collection to make way for summer renovations, where can one hire a large posse of librarians?
