Description

The CFR Index and Finding Aids is revised once a year and contains:

• A subject/agency index for rules currently codified in the Code of Federal Regulations (CFR).
• A list of agency-prepared indexes appearing in individual CFR volumes.
• A table of laws and Presidential documents cited as authority for regulations currently codified in the CFR.
• A list of CFR titles, chapters, subchapters, and parts.
• An alphabetical list of agencies appearing in the CFR.

The CFR or Code of Federal Regulations was originally 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 on 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.
