The bibliography lists books, articles, reports, and other materials on devices that convert print to speech, braille or other tactile output for use by blind persons. The material has been published since 1975. The bibliography is divided into three sections: (1) general works, including background information, history, works treating several types of reading machines, and bibliographies; (2) the development, use, and evaluation of specific reading machines (such as braille cassette recorders and braille word processors); and (3) names and addresses of companies involved in current development and distributions of such devices.
