Within the public, academic, and school libraries the use of specific types of materials was examined, for example, audio-visual, reference and bibliographic materials and different types of catalogs. The physical layout and arrangement of the libraries, and their influence on use and non-use was also considered. The factors inhibiting the use of libraries include the geographical distribution of users, the location of the library within the community and the educational abilities and literacy levels of the readers. The levels of usage included are: academic - professional and faculty members, postgraduate, undergraduate, research and administrative levels; public - adults and children, student, professional and business; and special provision for handicapped or homebound readers. Information for the bibliography was gathered from a search of the published literature, unpublished materials, material obtained from letters to library schools, and published letters, and relevant published indexing and abstracting services, e.g. "Library and Information Science Abstracts,""Library Literature," and "ERIC."
