For 100 years, the Congressional Research Service (CRS) has been charged with providing nonpartisan and authoritative research and analysis to inform the legislative debate in Congress. This has involved a wide range of services, such as written reports on issues and the legislative process, consultations with Members and their staff, seminars on policy and procedural matters, and congressional testimony. The Government and Finance Division at CRS took a step back from its intensive day-to-day service to Congress to analyze important trends in the evolution of the institution-its organization and policymaking process-over the last many decades. Changes in the political landscape, technology, and representational norms have required Congress to evolve as the Nation's most democratic national institution of governance. The essays in this print demonstrate that Congress has been a flexible institution that has changed markedly in recent years in response to the social and political environment.

Addressing a field that has been dominated by astronomers, physicists, engineers, and computer scientists, the contributors to this collection raise questions that may have been overlooked by physical scientists about the ease of establishing meaningful communication with an extraterrestrial intelligence. These scholars are grappling with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected. By drawing on issues at the core of contemporary archaeology and anthropology, we can be much better prepared for contact with an extraterrestrial civilization, should that day ever come.
