An evaluation of the E-Z cassette player was conducted for the National Library Service (NLS) for the Blind and Physically Handicapped to determine if the player is suitable for readers who either had no previous experience with cassettes or who cannot operate a standard NLS cassette player. Players were distributed to volunteer library patrons and personalized instruction was provided in operating the machines, which are designed to play the standard four-track monaural cassette used in the Talking Book program and to handle as many functions automatically as possible. Participants discussed their reactions to the equipment and completed a questionnaire to identify what they liked and disliked about the machine. Records were also kept of machine malfunctions and other problems. Findings indicate that the machine was popular with elderly readers because of its automatic side-advance feature and because there are only two controls necessary in normal use. The only major problem found involved the microprocessor, which does not function properly after voltage change in the lines. Appendices include tables displaying data on machine operation and controls, common problems, and general acceptability and machine use, as well as a participant profile and the participant questionnaire.
