This is one of my favorite bits of ephemera, the Personal Library Kit. It includes a rolling date stamper, library cards and pockets, pad and pencil. Now you can loan out your books like a true professional. You might just need to invest in the Librarian pin while your at it. $20 (via fredflare.com)
