The Allegheny County Library Association (ACLA) is a federated library system of 46 public libraries delivering service in more than 70 locations. Member Libraries include the Carnegie Library of Pittsburgh, which has 19 locations, and 45 other libraries and their branches located outside the City of Pittsburgh throughout Allegheny County. Each library is independent and has its own board of directors; as a consortium they share a countywide catalog, jointly offer downloadable books, audios, and videos as well as online databases, and provide a diverse calendar of programming events. The eiNetwork supports the automated library operations, Internet access, and free Wi-Fi services available at all county libraries. Through its coordination, ACLA expands the resources of local libraries beyond what they could accomplish individually.
