Known as the official handbook of the federal government, this annual resource provides comprehensive information on the agencies of the legislative, judicial, and executive branches, as well as quasi-official agencies, international organizations in which the United States participates, boards, commissions, and committees. Each agency's description consists of a list of principal officials; a summary statement of the agency's purpose and role in the federal government; a brief history of the agency, including its legislative or executive authority; and a description of consumer activities, contracts and grants, employment, and publications.
