A study was made to determine the effectiveness and acceptability of cassette books for blind and physically handicapped readers. Commissioned by the Ohio State Library, an interview survey was conducted to 300 diversified users from the Cleveland and Cincinnati-Hamilton County Regional Libraries for the Blind and Physically Handicapped. The following conclusions and recommendations resulted: (1) The great majority of handicapped people prefer books recorded on cassette; (2) there are still technical problems to be solved; (3) the Library of Congress should continue to work with tape manufacturers to design a sturdier, more trouble-free cassette; (4) the Library of Congress should reconsider its decision to supply only the audiotape players; (5) immediate steps should be taken to broaden the range of materials available in cassette form; (6) a pilot series of adult education courses on cassette tape might be undertaken; (7) if the use of cassette tapes becomes more widespread, the regional libraries must be prepared to invest time and staff in more rigorous inspection; (8) fund sources should be sought to provide additional staff support for the Regional Libraries for the Blind and Physically Handicapped.
