To build a digital government for the next century, the nation needs to assemble and employ an array of talents and resources. Evolving technologies will surely continue to be a catalyst and agent of change, generating increasing need for technological research and development. The change that technology brings with it demands equally serious research investments into questions of political, institutional, and organizational response and adaptation. To meet these challenges, NSF's Digital Government research program must foster multidisciplinary, multi-method research. This research program must extend across time and physical and political geography, and be linked in mutually beneficial ways to the goals and the practice of government.
