Tired of your friends not returning books you lend them in a timely manner? Feeling like your book collection is a personal library? Get the DIY Library Kit and turn your personal library into an actual library. The kit comes with everything you need to start charging your buddies late fees: 20 self-adhesive pockets, 20 checkout cards, date stamp, inkpad, and pencil. Just add books, a mousy librarian, microfiche machine, and that weird scanner thing by the door that beeps even though your book is checked out properly and you’re good to go.
