Eds. Andrew Chadwick and Philip N. Howard. The politics of the Internet has entered the social science mainstream. Internet politics and policy are continually hitting the headlines; from debates about the medium's impact on parties and election campaigns following the momentous US 2004 presidential contest to concerns over international security, privacy and surveillance post 9/11. The Handbook of Internet Politics is concerned with theoretical and conceptual debates, political institutions and practices, and how the Internet creates new policy problems for liberal democratic and non liberal-democratic states, not to mention their roles in the global system. There has been a steady stream of high quality research literature in this field over the last five years and this Handbook calls upon contributions from some of the leading scholars in the field from the UK, Europe and US. Providing the first comprehensive overview of Internet politics, this will be a helpful companion to students and scholars of politics, international relations, communication studies and sociology.
