The Code of Federal Regulations is the codification of the general and permanent rules published in the Federal Register by the executive departments and agencies of the Federal Government.

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.
