Paralleling the rapid development of widely distributed information and computing technologies has been an accelerated demand by citizens for electronic access to government services and, conversely, a drive by government administrators to harness the cost, quality, and efficiency benefits that electronic service delivery offers. And alongside these phenomena have emerged a new set of opportunities and challenges in such areas as security, privacy, ethics, and more, to which governments and citizens have only begun to come to terms.

These landmark studies from the leading electronic government researchers worldwide enable libraries in academic, government, and other settings to provide a unified collection on such pressing topics as digital government, electronic justice, government-to-government, information policy, and cyber-infrastructure research and methodologies. This Premier Reference Source provides practitioners and academicians alike with the essential concepts relating to e-government and its implications within the global context.
