Because of concerns about the effect of internet blocking mechanisms, and the implications of censorship, many individuals and groups are working hard to ensure that the Internet, and the information on it, are freely available to everyone who wants it. This book documents simple circumvention techniques such as a cached file or web proxy, and also describes more complex methods using Tor, which stands for The Onion Router, involving a sophisticated network of proxy servers.
