This reference circular lists organizations that provide a variety of direct services to blind and visually impaired persons, including advocacy and employment programs, assistive devices, and publications offered in special format. Many of the organizations also offer guidance to families of blind and visually impaired persons and training for professionals. Many publish journals, monographs, catalogs, and pamphlets, and the major publications are identified in this circular. The first of three sections lists the organizations alphabetically with annotations that describe the services they provide. The second section presents directories and other publications that list agencies, services, and resources for blind and visually impaired persons. These publications contain the names of organizations that serve blind and visually impaired persons in the United States and in other countries; organizations that have braille music collections and tactile map collections; and producers and distributors of braille and large print reading materials and assistive devices for reading and other related activities. Section III lists state-level agencies that administer public programs providing special education and rehabilitation services. (MAB)
