Gis\xe8le Sapiro traces the emergence of a transnational literary field in the twentieth century by analysing the book market for translations. Sapiro defines the notions of \u2018cosmopolitan\u2019, \u2018international\u2019, \u2018transnational\u2019, \u2018global\u2019 and \u2018world\u2019 from a historical and sociological point of view in order to show that they should not be understood to be in opposition to the national perspective. She then tackles the emergence of a transnational literary field and its inherent inequalities through the circulation of books and the increasing practices of translation as well as the formation of a World literary canon after the Second World War.
