Huh, this is a really cool tumblr
Circulation slips are/were one of my favorite parts of working in a library; if I saw a cool book that hadn’t been checked out since like 1964, I’d pull it out of the stacks and scan it into the in-house use records. It probably didn’t do anything to ~save~ the books, but it made me feel better. (And apparently we stopped using date stamps the year before I started working there, so for four years I’ve been hand-writing the dates and initialing them. Some professors use the same VHS tapes over and over again—you can set your watch to them—and I’ll see A.W. on the slip going two, three years back. ‘Oh,’ I don’t ever say to them, ‘I checked this out for you in 2009, huh.’)
