“No one had a clear sense of the nature of Internet censorship until now. This extraordinary work maps the unfreedom of the Net. Unfortunately, that state is becoming the norm.”
— Lawrence Lessig

“In Access Denied an unlikely avant-garde of scholars, lawyers, hacktivists, and computer programmers come together to combat efforts by repressive regimes, corporate firms, and intelligence agencies to surveil, filter, and block the Internet. Through critical analysis, regional surveys, and the use of innovative software, the authors reveal the penumbra of a networked global civil society emerging from the Dark Side’s efforts to eclipse the Internet. Everyone who supports open thought and the free flow of information should read Access Denied.”
— James Der Derian, Director, Global Security Program, Watson Institute for International Studies, Brown University

“The Web provides everybody with access to information. That makes those in power nervous. Transparency is the best defense against further narrowing of information access and the starting point for rolling back existing barriers. Access Denied provides the definitive analysis of government justifications for denying their own people access to some information and also documents global Internet filtering practices on a country-by-country basis. This is timely and important.”
— Jonathan Aronson, Annenberg School for Communication, University of Southern California
