This law school casebook starts from the premise that cyberlaw is not simply a set of legal rules governing online interaction, but a lens through which broader issues can be re-examined. The book goes beyond simply plugging Internet-related cases into a series of pre-existing categories, instead emphasizing conceptual debates that cut across the areas of doctrine touched by cyberspace. It also uses the rise of the Internet to encourage readers to reconsider various assumptions in traditional legal doctrine, providing training in Internet-related legal issues while making the argument that cyberlaw is a coherent and useful field of study.
