Part I contains an edited documentation of 585 reviews (and supporting documents) of 44 of Georg Kaiser's plays which were premiered from 1915-45. This documentation makes available to scholars reviews collected from archives and libraries in Canada and Europe. Part II, a commentary, discusses the major points raised in the reviews and examines problems of interest to modern critics such as Kaiser's breakthrough as a dramatist, his difficulties with the censors and the Nazis and the categorisation of his plays.
