Government Structure

The federal government is a large and complex organization. To help better understand its structure and key leadership positions, please start with the following resources:

The Manual provides comprehensive information on the agencies of the legislative, judicial, and executive branches. It also includes information on quasi-official agencies; international organizations in which the United States participates; as well as boards, commissions, and committees.

Federal Register
Published daily, the Federal Register is the official journal of the federal government. It contains all federal government agency rules, proposed rules and public notices.
