We took a look at the archival boxes we made yesterday, and they looked good. Craig then took me up to the closed stacks to show me some of the maps, banners, posters, and other rare materials collected by the University; Craig repaired some of them himself. I then went back to placing protective covers on the tagged books in the closed stacks using the Colibri machine and finished the entire aisle. Finally, I created a couple more customized four-flap enclosures from scratch. The precise measurements are time-consuming, but I enjoy the work. I had a great week in the preservation department.
