Book excerpt: "There is no such thing as 'the ivory tower.' Rather, there sit side by side numerous windowless towers of knowledge, each seeming to have only a small entrance and no discernable exit." -Paul Martin Multilingual, multicultural, and vast, Canada enjoys a rich diversity of literatures. So, why does "Canadian Literature," as it has been taught, fail to encompass a common geography, history, and government, yet reveal the diverse experiences of its immigrants, long-term residents, and original peoples? Martin's research-interviews with 95 professors in 27 universities-maps the institutional chasms in communication and the nature of their persistence. His own example of venturing out from his "tower" to dialogue with colleagues shows a way toward cultivating a conception of the literatures of Canada that is expansive and inclusive. Canadianists, professors of English, French, Postcolonial and Comparative Literatures, and leaders in education will profit from Martin's frank investigations.
