In this interview, historian of books Roger Chartier discusses some of the main concepts and findings of his research in light of the development of digital reading. The shift induced by the emergence of digital reading devices is replaced within the scope of major long-term transformations in the history of books. Having emphasized the materiality of digital reading devices, Chartier explains how they have been changing existing modes of reading as well as forms of textuality and intertextuality, and more broadly revolutionizing the economic structures of the book market and the conditions of intellectual work and of its dissemination.
