Mosaic , a quarterly magazine devoted to "the comparative study of literature and ideas," was founded at the University of Manitoba in 1967 under the editorship of Kenneth McRobbie. It publishes only critical and interpretive essays. One of the four issues a year is now devoted to a single topic of concern to interdisciplinary scholars, eg, "From an Ancient to a Modern Theatre"; "The Novel and Its Changing Forms"; "The Eastern European Imagination in Literature." An unusual feature of Mosaic is that many issues are republished in book form.
