Educational publishing sits at the intersection of industry, culture and education. Pedagogical aims must be balanced with the need for publishers to make a profit, while also acknowledging Canadian national identity and culture. The events of central interest are related to the tensions between two publishers’ associations in the wake of the sales, in 1970, of Canadian publishers Gage and Ryerson Press to American interests. The Canadian Book Publishers’ Council was comprised mainly of American branch plants and the Independent Publishers Association membership was Canadian-owned publishing companies. The two associations became bitter rivals, engaging in ‘fratricidal warfare’, as they lobbied the provincial and federal governments and fought to maintain their places in the textbook market. About 65% of total sales revenues from publishing in Canada came from textbook sales in this period. Both governments and commercial interests had to balance Canadian sovereignty with commercial gain and educational goals.
