To ensure a separation of powers, the U.S. Federal Government is made up of three branches: the Executive, Judicial and Legislative.
The United States Government Manual is the official handbook of the Federal Government and provides 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; and boards, commissions, and committees. It begins with reprints of the Declaration of Independence and the U.S. Constitution.
