National Library Service for the Blind and Physically Handicapped: Digital Plans and Progress‪.‬

BACKGROUND The increasing prevalence, popularity, and economy of digital electronics motivates NLS to work rapidly toward a completely digital audio service. This means using digital methods throughout the production and distribution stream, from studio recording of digital original masters and digital collection management to digital product distribution and playback. The length and complexity of the transition are consequences of size. NLS annually circulates about 22,000,000 audio books and magazines nationwide and supports the use of about 721,000 cassette playback units. Further information on NLS, including the agency's mission, organization and history can be found on the NLS website; see, particularly, the area titled About NLS, where "Basic Facts About NLS" and other summary information can be found.
