In order to develop a profile of the readership served by the National Library Service for the Blind and Physically Handicapped (NLS), and to identify readers' interests and concerns as an aid to future program planning, a users survey was conducted during the autumn of 1979. After a questionnaire was designed and tested, NLS members were surveyed by mail, or by phone when necessary. In December of 1979 a supplemental questionnaire was sent to regional and sub-regional libraries in the NLS network. The major findings of the surveys related to user characteristics, use of library service, equipment use, reading materials, user assessment of library services, and the perspectives provided by network libraries. The recommended actions to be taken based on the survey results include: a campaign to attract non-white, less educated, and low income readers to NLS; a review of the process by which readers are introduced to NLS; and the development of a method for obtaining input from readers on a regular basis. The survey findings are presented in 83 tables, and copies of the user and network library surveys are provided as appendices. (JL)
