The Open University of Great Britain relies heavily on broadcasting as a mode of instruction, but increased course offerings are making it impossible to broadcast each lesson more than once. To reach students unable to view the original broadcast, video cassette reorder systems were tested in six community study centers as part of a 1974 pilot study. Student use patterns, equipment reliability, and variations among the centers were monitored. By the end of the year, 258 playbacks had been attended by 496 students. It was concluded that, if small technical difficulties could be overcome and initial capital expenditures reduced, a central library of video cassettes could become part of the Open University of the future.
