Open Educational Resources: Government sources

USA.gov is the U.S. government's official web portal to all federal, state, and local government web resources and services.

The Congressional Budget Office produces independent, nonpartisan, impartial analyses of budgetary and economic issues to support the Congressional budget process. CBO does not make policy recommendations, and each report and cost estimate summarizes the methodology underlying the analysis.

The Government Accountability Office provides fact-based, nonpartisan information to Congress. Often called the "congressional watchdog," GAO investigates federal spending and performance.

GAO reports are easily available; objective, fact-based, nonpartisan, non-ideological, fair, and balanced; tend to be longer, more in-depth, and more critical than CRS reports; full of useful charts and statistics; might be one particular aspect of a policy/law; and make a recommendation regarding the policy.

The Congressional Research Service offers Congress research and analysis on all current and emerging issues of national policy. CRS makes no legislative or other policy recommendations to Congress; its responsibility is to ensure that Members of the House and Senate have available the best possible information and analysis on which to base their policy decisions.

CRS reports are widely regarded as in depth, accurate, objective, and timely, but as a matter of policy they are not made available to members of the public by CRS, except in certain circumstances.

The collection of the National Library of Education focuses on education, but also includes fields such as law, public policy, economics, urban affairs, sociology, history, philosophy, and information science.

The Homeland Security Digital Library is the nation's premier collection of documents related to homeland security policy, strategy, and organizational management. The HSDL is sponsored by the U.S. Department of Homeland Security's National Preparedness Directorate, FEMA and the Naval Postgraduate School Center for Homeland Defense and Security.

The U.S. Geological Survey serves the Nation as an independent fact-finding agency that collects, monitors, analyzes, and provides scientific understanding about natural resource and natural hazard conditions, issues, and problems.
