I don’t know about you, but I’m often lax about pulling the receipts out of my library books. I use them as book marks and then leave them in when I return them, figuring the library staff or book gnomes or somebody will pull them out and recycle them. Well, this receipt appeared in a book my mom got from the library, and I’m not sure I’ll ever think of leaving receipts in books again.

In case your library doesn’t do it this way, the receipt lists all the books the person checked out in that session. I’ve ripped the patron’s name off to protect (going out on a limb here) her identity.
