The Code of Federal Regulations (CFR) is the codification of the general and permanent rules published in the Federal Register by the executive departments and agencies of the Federal Government. It is divided into 50 titles that represent broad areas subject to Federal regulation. Each volume of the CFR is updated once each calendar year and is issued on a quarterly basis.
Titles 1-16 are updated as of January 1st
Titles 17-27 are updated as of April 1st
Titles 28-41 are updated as of July 1st
Titles 42-50 are updated as of October 1st
Each title is divided into chapters, which usually bear the name of the issuing agency. Each chapter is further subdivided into parts that cover specific regulatory areas. Large parts may be subdivided into subparts. All parts are organized in sections, and most citations in the CFR are provided at the section level. A list of agencies and where they appear in the CFR may be found in Appendix C of the U.S. Government Manual.
The online CFR is a joint project authorized by the publisher, the National Archives and Records Administration's (NARA) Office of the Federal Register (OFR), and the Government Printing Office (GPO) to provide the public with enhanced access to Government information.
CFR volumes are added to GPO Access concurrent with the release of the paper editions. When revised CFR volumes are added, the prior editions remain on GPO Access as a historical set. Some CFR records on GPO Access date back to 1996; all titles are available from 1997 to the current year. documents are available as ASCII text and PDF files.
NOTE: "[Reserved]" is a term used as a place holder within the Code of Federal Regulations. An agency uses "[Reserved]" to simply indicate that it may insert regulatory information into this location some time in the future. Occasionally "[Reserved]" is used to indicate that a portion of the CFR was intentionally left empty and not accidentally dropped due to a printing or computer error.
Due to the update schedule of the CFR, the List of Sections Affected (LSA) provides a cumulative list of CFR sections that have been changed at any time since each CFR title was last updated.
documents are available in PDF and ASCII text formats. The Code of Federal Regulations is available on GPO Access from 1996 (partial) forward.
