The OpenNet Initiative’s (ONI) mission is to “identify and document Internet filtering and surveillance, and to promote and inform wider public dialogs about such practices.” Access Denied: The Practice and Policy of Global Internet Filtering is one of their texts that effectively draws together years of their research, and presents it in an accessible and useful manner for researchers, activists, and individuals who are simply interested in how the Internet is shaped by state governments.

The text is separated into two broad parts – the first is a series of essays that situate the data that has been collected into a quickly accessible framework. The authors of each essay manage to retain a reasonable level of technical acumen, even when presenting their findings and the techniques of filtering to a presumably non-technical audience. It should be noted that the data collected includes up to 2007 – if you’re reading the text in the hopes that the authors are going to directly address filtering technologies that have recently been in the new, such as Deep Packet Inspection, you’re going to be a disappointed (though they do allude to Deep Packet technologies, without explicitly focusing on it, in a few areas). Throughout the text there are references to human rights and, while I’m personally a proponent of them, I wish that the authors had endeavored to lay out some more of the complexities of human rights discourse – while they don’t present these rights as unproblematic, I felt that more depth would have been rewarding both for their analysis, and for the benefit of the reader. This having been said, I can’t begrudge the authors of the essays for drawing on human rights at various points in their respective pieces – doing so fits perfectly within ONI’s mandate, and their arguments surrounding the use of human rights are sound.
