Code of Federal RegulationsThe CFR is the codification of the general and permanent rules published in the Federal Register by the departments and agencies of the Federal Government. 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 Publishing Office (GPO) to provide the public with enhanced access to Government information. There is an eCFR that is continually updated online (https://www.ecfr.gov/), but it is not the official legal edition.
