The current study explores the international copublishing of literary books, in particular that of recent Canadian English novels translated into French by French Canadian publishers and copublished in France. Following a socio-traductological approach, and based on four case studies involving a range of publishers as well as translators, the research highlights the diversity in translation practices while identifying areas of overlap. The article also tackles the following questions: the potential impact of the copublishing model on the linguistic norm adopted by Quebec translators and publishers; how co-publishing shapes and is at once informed by the balance of power between the two editorial fields; to what extent perceptions about copublishing experiences by the involved parties are influenced by their position in the editorial field.
