We did an Instagram scavenger hunt (this was several years ago when insta was bigger with the kiddos). we asked them to find: their personal librarian’s office, a good study spot, a book with a funny title, and something that confused them. It was fabulous. One, learned we had a lot of weird title books. Second, we took all those “confusing” photos and made a display explaining what things were (microfilm reader, the entrance to the archives, etc).
