Literature has experienced two great medium shifts, each with profound implications for its forms, genres, and cultures: that from orality to writing, and that from writing to printing. Today we are experiencing a third shift, from printed to digital forms. As with the previous shifts, this transformation is reconfiguring literature and literary culture. The Cambridge Companion to Literature in the Digital Age is organized around the question of what is at stake for literary studies in this latest transition. Rather than dividing its chapters by methodology or approach, this volume proceeds by exploring the major categories of literary investigation that are coming under pressure in the digital age: concepts such as the canon, periodization, authorship, and narrative.
