While technology is increasingly a central component for the operation of government, its role is poorly understood. This ground-breaking and insightful book uniquely utilizes Foucault's governmentality approach to examine the nature of contemporary, technologically-facilitated government. Drawing on six detailed case studies of e-government in welfare, health and taxation, the book demonstrates that information technology is more than just a tool for politicians and policy-makers, but contributes to the very substance and reconfiguration of public administration, public policy, power and citizenship. Moreover, governmental changes are analysed in terms of networks, risk, speed, complexity, power and citizenship.
