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.
