What does circulation have to do with a library?

When you have questions such as "Where do I go to get a replacement library card?" or "How much do I owe the library?", the Circulation Desk is where to go. The Circulation department is responsible for performing functions such as check-ins, check-outs, renewing library materials, monitoring the self-check machines, receiving payment for fines, and library card registration. The Circulation Department is also responsible for managing the re-shelving of all returned materials, and maintaining the order of the various collections housed in the library.
At the Gibson Library, the Circulation Department head is Greg Reyes.
