The Cobb County Public Library System (CCPLS) is a system of 16 public libraries in Cobb County, Georgia, United States, excluding its second-largest city of Smyrna, which runs its own Smyrna Public Library. CobbCat.org is the online database of all CCPLS holdings. The CCPLS uses an interlibrary loan system among all 16 branches, and allows for loan requests from other counties and areas through WorldCat. Those with a valid library card in the Cobb Country Library system can reserve materials online and pick them up in their local library. Books may be returned at any library in the system.
