The Federal Register (since March 14, 1936), abbreviated FR, or sometimes Fed. Reg., is the official journal of the federal government of the United States that contains most routine publications and public notices of government agencies. It is a daily (except holidays) publication.
The Federal Register is compiled by the Office of the Federal Register (within the National Archives and Records Administration) and is printed by the Government Printing Office. The final rules promulgated by a federal agency and published in the Federal Register are ultimately reorganized by topic or subject matter and codified in the Code of Federal Regulations (CFR), which is updated annually.
