"Managing the Infosphere" examines the global world of communications as a mobile space that overlaps uneasily with the world of sovereign, territorial nation-states. Drawing on their expertise in geography, political science, international relations, and communication studies, the authors investigate specific policy problems encountered when international organizations, corporations, and individual users try to "manage" a space that simultaneously contradicts and supports existing institutions and systems of governance, identity, and technology. The authors argue that the roles of these systems in cyberspace cannot be fully understood unless they are seen as mutually constituting each other in specific historical structures, institutions, and practices. With vision and insight, the authors look beyond the Internet to examine the entire networked world, from cell phones and satellites to global tourism and business travel.
