The Code of Federal Regulations (C.F.R.) is an annual codification of the general and permanent rules published in the Federal Register by the executive departments and agencies of the federal government. The purposes of the C.F.R.are to present the official and complete text of agency regulations in one organized publication and to provide a comprehensive and convenient reference for those researching federal regulations.
The C.F.R. is divided into 50 titles representing broad areas subject to federal regulation. Each title is divided into chapters that are assigned to agencies issuing regulations pertaining to that broad subject area. Each chapter is divided into parts, and each part is then divided into sections -- the basic unit of the C.F.R.
The C.F.R. is keyed to and kept up-to-date by the daily Federal Register. These two publications must be used together to determine the latest version of any given rule. When a federal agency publishes a regulation in the Federal Register, that regulation often is an amendment to the existing C.F.R.
The approximately 200 C.F.R. volumes are revised at least once a year on a quarterly basis as follows:
Titles 1 -- 16 as of January 1
Titles 17 -- 27 as of April 1
Titles 28 -- 41 as of July 1
Titles 42 -- 50 as of October 1
The revision date of each volume is printed on the cover, and at the top of every even-numbered page. Each year's cover is a different color for quick reference.
The C.F.R. is available online at:
The Chickasaw Nation Law Library maintains the current year of the C.F.R. in print in the Reference section. The CFR Index and Finding Aids volume contains an alphabetical subject index as well as an alphabetical list of agencies appearing in the C.F.R. Other finding aids, including a list of C.F.R. Titles, Chapters, Subchapters, and Parts, is also included.
