A county public library is a publicly funded institution that provides access to books, digital media, educational resources, and community programs for residents of a specific county. These libraries aim to support literacy, lifelong learning, and community engagement by offering free or low-cost services to the public. In addition to lending books, county public libraries often provide internet access, research assistance, children's activities, and meeting spaces. Membership is typically free for county residents, and the library is usually governed by a local board or county authority.
