Code of Federal Regulations

Once a final federal regulation is published in the Federal Register, it is then codified in the Code of Federal Regulations. C.F.R. is the abbreviation. The C.F.R. is organized by "Title" -- there are 50 of these. Each title represents a broad area that is subject to regulation; for example, Title 37 is Patents, Trademarks, and Copyrights. Each title further breaks down into chapters, whose names usually correspond to the regulation-issuing agency. For example, Chapter 1 of Title 37 is the US Patent and Trademark Office, and Chapter 2 is entitled Copyright Office. Each chapter of the C.F.R. further breaks down into parts and sections.
