This essay charts key aspects of the development of canonical literary criticism in the English-speaking Caribbean. It argues that a full understanding of the ways in which proliferating critical statements coalesced into a major body of evaluative work across the decades, from the 1930s through the 1970s, needs to account for the diverse and intersecting communicative platforms the criticism relied upon. The burgeoning criticism responded to the blossoming of anglophone Caribbean literature in the post World War II period via print venues such as Bim in Barbados, Kyk-over-al in Guyana, and the Jamaica Journal and Caribbean Quarterly in Jamaica. In addition, during the decades of the 1940s and 1950s, the BBC literary radio programme Caribbean Voices functioned as a platform for the production and dissemination of Caribbean literary and cultural criticism. As such, the development of the critical canon in the anglophone Caribbean is not only the story of intersecting and mutually supportive media, print and electronic, but also the story of transatlantic knowledge flows. The essay therefore proposes that the intersection of print and electronic media and the robust transatlantic knowledge flows call into question, in the contemporary moment, any enduring distinction between those putative binaries that energized so many of the critical arguments of the period, viz. home vs. exile, oral vs. scribal, and folk criticism vs. cosmopolitan practice.
