This directory in chart form identifies Ohio public library services and resources which can be used by people with vision, hearing, mobility, and learning impairments, and those isolated because of illness or age. Data were gathered from a survey of 226 public libraries in March 1980. Introductory information summarizes the responsibility of the State Library of Ohio for library service to people with disabilities and to older people, lists the counties served by the two regional libraries for the blind and physically handicapped, and defines the items listed under the following categories on the charts: services offered by libraries, services for the deaf and hearing impaired, materials and equipment, and building access features. Arrangement of the charts is alphabetical by county and location of library. (Author/FM)
