The Lewiston Public Library is a member of the Nioga Library System, a non-profit cooperative library system serving the public libraries in three counties. The library system takes its name from the counties that it serves: Niagara, Orleans, and Genesee. The system, which consists of twenty-one public libraries, is one of twenty-three similar systems in New York State. It receives most of its financial support through the New York State Department of Education. The Nioga Library System, which was chartered in 1958, helps to provide improved informational services to all residents of its three county area.
