The material in this collection pertains not only to an individual, Richard Schechner, but also to TDR, The Drama Review, a scholarly journal concerned with the broad range of performance in society and in the arts. Schechner, a renowned scholar, director, writer, and educator, edited The Drama Review from 1962-1969 and again from 1986 to the present date. Particularly in the 1960s, and again in the 1990s, both Schechner and TDR challenged traditional, prevailing ideas about theater-what it is, how it should be presented, and the ritual and ideals behind it. Schechner argued for thinking of "performance" as an all-encompassing genre with "theater" as one of its sub-categories. He is widely recognized as the founder of "performance studies" as an academic discipline. In the process of working out what performance studies is, Schechner and his colleagues at New York University created new ideas and new ways of thinking that still affect today's world of performance, theater, dance, and the social sciences. As "the journal of performance studies," TDR did much to shape the new discipline.
