The Code of Federal Regulations (C.F.R.) is the codification of the general and permanent rules and regulations published in the Federal Register by the executive departments and agencies of the federal government.
The C.F.R. is organized into 50 titles which represent broad topics. Each title is divided into chapters which usually bear the name of the issuing agency. Each chapter is further subdivided into parts covering specific regulatory areas. Large parts may be subdivided into subparts. All parts are organized in sections.
The C.F.R. contains only the text of final rules and regulations themselves and does not include any of the very important summary, explanatory and documentary information published in the Federal Register.
Most online versions of the C.F.R. are updated within 24 hours.
The California Code of Regulations (C.C.R.) is the official compilation and publication of the regulations adopted, amended or repealed by state agencies. Similar to the arrangement of the Code of Federal Regulation, the C.C.R. is compiled into 28 Titles and organized into Divisions containing the regulations of state agencies.
Its role is similar to the C.F.R. Unlike the Federal Register, California regulations are not normally published in the Notice Register, meaning that until they are codified in the C.C.R. they must be obtained from the individual agencies or elsewhere.
