History.
The CFR was authorized by President Franklin D. Roosevelt on October 11, 1938, as a means to organize and maintain the growing material published by federal agencies in the newly mandated Federal Register. The first volume of the CFR was published in 1939 with general applicability and legal effect in force June 1, 1938.
The Office of the Federal Register (OFR) began publishing yearly revisions for some titles in 1963 with legal effective dates of January 1 each year. By 1967 all 50 titles were updated annually and effective January 1.
The CFR was placed online in 1996. The OFR began updating the entire CFR online on a daily basis in 2001.
