Since the most immediate and efficient method of illustrating lectures on the history of the theatre is by using visual aids, theatre historians should learn the best ways of creating and using such aids as slides, slide/tape packages, commercially produced films and filmstrips, and video cassettes and tapes. These aids have characteristics which make them appropriate for different facets of a theatre program, especially in classroom instruction. However, some of them may also be used successfully in reporting research results, particularly those of performance reconstructions. Theatre historians must give more attention to reconstruction through actual performance and to recording those reconstructions for the benefit of other historians. Thus, graduate theatre programs should include basic photography and videotaping techniques. (JM)
