Most books about cyberspace extol its virtues and wonders. Code isn’t one of them. Lawrence Lessig has written an important and challenging book that examines the legal and policy issues about the code of cyberspace, i.e., its hardware and software. This code, he warns, provides new, easy, and invisible ways to control and regulate our behavior. It puts vastly greater power in the hands of not only government but the commercial sector as well.

Lessig has the credentials to be taken seriously. He specializes in constitutional and cyberspace law at Harvard Law School. He was asked by federal District Judge Thomas Penfield Jackson to file as amicus curiae in the Microsoft antitrust case.
