When a law is passed, Congress grants federal agencies the authority to promulgate rules and regulations to interpret the law. These regulations have the force and effect of law. The federal rules and regulations are first published, chronologically, in the Federal Register. The Code of Federal Regulations codifies the general and permanent rules published in the Federal Register. Below are links to both the Federal Register and the Code of Federal Regulations. For a more detailed description of the regulatory process, see A Guide to the U.S. Federal Legal System.
