Library Circulation is the function of lending library materials (books, serials, sound recordings, moving images, cartographic materials, etc. that are owned by a library) to the users of the library. Library Circulation includes checking out library materials to library users, renewing the borrowed items, reserving checked out items for the patron, checking in materials returned, checking the materials for damage at the time of return, and if found damaged then giving that to the responsible staff for repair and when a repair is not possible then a replacement, renewal of materials, receiving payment of fines for damaged and overdue materials and payment for subscription to the library and other charges, maintaining order in the stacks by re-shelving the library materials by call number given by classification systems, such as Library of Congress Classification (LCC) or Dewey Decimal Classification (DDC) system. There is a Circulation Desk, a long counter usually located at the main entrance of the library to carry out library circulation activities. It is the service point to register for the library card, check out, renew, and return library materials. Library staff at the circulation desk also provides basic search and reference services in the use of the library and placement of information resources.
