The Code of Federal Regulations (C.F.R) is the codification of the regulations that are enacted by federal agencies. Regulations tell how to implement and interpret the laws, which are found in the United States Code (U.S.C.). Since the C.F.R. is published annually but regulations are released more frequently than once a year, researchers can use the eCFR which is updated daily with the latest additions to the CFR; however, the eCFR is not the official legal version of the CFR.
Regulations are first published in the Federal Register, which is updated daily.
