A visible presence for some two decades, electronic literature has already produced many works that deserve the rigorous scrutiny critics have long practiced with print literature. Only now, however, with Electronic Literature by N. Katherine Hayles, do we have the first systematic survey of the field and an analysis of its importance, breadth, and wide-ranging implications for literary study. Hayles’s book is designed to help electronic literature move into the classroom. Her systematic survey of the field addresses its major genres, the challenges it poses to traditional literary theory, and the complex and compelling issues at stake. She develops a theoretical framework for understanding how electronic literature both draws on the print tradition and requires new reading and interpretive strategies. Grounding her approach in the evolutionary dynamic between humans and technology, Hayles argues that neither the body nor the machine should be given absolute theoretical priority. Rather, she focuses on the interconnections between embodied writers and users and the intelligent machines that perform electronic texts. Through close readings of important works, Hayles demonstrates that a new mode of narration is emerging that differs significantly from previous models. Key to her argument is the observation that almost all contemporary literature has its genesis as electronic files, so that print becomes a specific mode for electronic text rather than an entirely different medium. Hayles illustrates the implications of this condition with three contemporary novels that bear the mark of the digital.
