What To Do With Old Catalogue Cards

Some kids have never even used a card catalogue. I never really liked them. I'm short and I was a short kid and the upper drawers were always annoying. Now there's a huge surplus of the cards. Librarians at the University of South Carolina are opening a contest to see what people can make with the obsolete cards.

I'd love to see some flip books, if the cards aren't too stiff for that. I made a couple in dictionaries when I was a kid. It might be cool to try again with more complex pictures. And I'd use catalogue cards as bookmarks. I have an old sign-out library card I'm using as a bookmark currently.
