An avalanche of single-author studies has appeared as a result of the expansion of the American university system since the 1960s, the growth of the “theory” industry, the triumph of the specialist and decline of the generalist, the proliferation of small academic presses, and the increasing pressure on professors (even in many small colleges) to publish. These monographs function, as a rule, as part teaching aid, part research tool, and part undergraduate crib sheet. The best-known series of these monographs is probably the Twayne (U.S., English, World) Authors Series, which started in the late 1950s and now includes over 150 authors deemed securely canonical. Routledge's Studies in Modern Drama is a more modest effort (the front matter of James Fisher's The Theater of Tony Kushner lists only ten other titles, mostly monographs). Fisher's comprehensive volume is very much in the Twayne tradition, providing a brief biography of the author, a dash of historical background, a study of the author's works, a production history, and an extensive bibliography, all rendered in a style accessible to specialist and nonspecialist alike.
