'This is a dazzling book; in scope, in depth, in the originality of its approach and in the crisp confidence of its style. Its place in the study of particular disciplines is clear, but in the broader picture, it is difficult to think of anyone engaged in intellectual work at the end of the twentieth century who would not be the better for reading it.' - Convergence: The Journal of Research into New Media Technologies'a much needed lexicon for scholars to draw upon.' - C.Jan Swearingen, Texas A & M University
