Book excerpt: This book is about the politics of cyberspace. It shows that cyberspace is no mere virtual reality but a rich geography of practices and power relations. Using concepts and methods derived from the work of Michel Foucault, Jeremy Crampton explores the construction of digital subjectivity, web identity and authenticity, as well as the nature and consequences of the digital divide between the connected and those abandoned in limbo. He demonstrates that it is by processes of mapping that we understand cyberspace and in doing so delineates the critical role maps play in constructing cyberspace as an object of knowledge. Maps, he argues, shape political thinking about cyberspace, and he deploys in-depth case studies of crime mapping, security and geo-surveillance to show how we map ourselves onto cyberspace, inexorably and indelibly. Clearly argued and vigorously written this book offers a powerful reinterpretation of cyberspace, politics, and contemporary life.
