A directory of Ohio libraries contains information about state, area, public, academic, school, special, and institutional libraries as well as multicounty interlibrary cooperative projects, state library advisory groups, and officers of associations. Directory information includes name and location of library, type of library, telephone number, the name of the director, and in the case of large organizations, names of heads of departments. In addition to directory information, statistical data is provided for public libraries, academic libraries, school library media centers, and the state as a whole. Data is given concerning collections, staffing, finance, and clientele. The section on public libraries is expanded to include a list of libraries by county as well as by city, and information on library organization and tax support, branches, bookmobile service, audiovisual materials, and statistics and distribution of tax moneys.
