The Code of Federal Regulations (CFR) is a continually revised arrangement of all general and permanent federal rules by subject. It is organized into 50 titles, and each title contains rules in a general subject area. For example, agricultural rules are in Title 7. The CFR has been printed since 1938 and it is updated annually.
