The National Library Service for the Blind and Physically Handicapped (NLS), Library of Congress, administers a free library program for those unable to read standard printed materials, reproducing and distributing works in braille, recorded disc, and recorded cassette. Previous studies of the distribution network had identified costs and developed a centralized option for the storage and distribution of braille materials, with user services at regional centers. This study explores the implementation of the centralized services and the transitional period in the following sections: (1) introduction; (2) fundamental decisions; (3) automatic data-processing development; (4) equipment and facilities; (5) operations services; (6) setup; (7) beginning operations; (8) monitoring operations; (9) estimated costs; and (10) planning and control. Eight exhibits illustrate the process. Five appendixes provide details of estimated costs and implementation needs. (SLD)
