The materials listed in this reference circular are recommended to libraries and organizations as basic resources for providing a current information service on visual impairments and physical disabilities. The selections, which are based on the holdings of the Reference Section of the National Library Service (NLS) for the Blind and Physically Handicapped, have been made on the basis of currency and authoritativeness. All titles are in print and, with a few exceptions, have been published since 1980. Pricing and ordering information have been provided in most cases. The following aspects of visual and physical disabilities are represented in book format: accessibility; aging; assistive devices; blindness and visual impairments; deaf-blindness; deafness and hearing impairments; developmental disabilities; education; employment and rehabilitative services; independent living; learning disabilities; legal rights; library services; medical aspects of disability; neurological disorders; orthopedic disorders; parent education; psychosocial aspects of disability; recreation; and travel. Directories and other reference resources which present information on assistive devices, agencies, programs and services, materials in special formats, and other supplemental references are also listed, as well as relevant periodicals, free and inexpensive materials, NLS resources, and information centers and online services. A list of other reference circulars and bibliographies published by the NLS reference section concludes the circular. (MAB)
