Federal administrative agencies are delegated the power to make rules/regulations by statute or Presidential Executive Order.
In order for this delegated responsibility to produce rules/regulations which have the force of law, agencies must abide by procedures which call for public notice and a period of public comment prior to finalization of the rule/regulation.
That procedure is accomplished by publication in the Federal Register of both proposed and final rules/regulations.
Final rules/regulations are then compiled into a Code of Federal Regulations which organizes rules/regs. into 50 code topics.
The Federal Regulatory Directory provides profile information including the history, structure, purpose, actions, and key contacts for every regulatory agency in the U.S. government.
