Incorporate book pockets into your library's circulation system. Once attached, the pocket has plenty of room to store time cards, and the outside, made of smooth manila kraft paper, is great for stamping at checkout or writing notes on. The side seam opening is ungummed, allowing patrons and librarians alike to insert and remove materials on a regular basis. And since they're unlabeled, they'll come in handy for projects at work or school as well as the library.
