The CFR is an official compilation of codified regulations.
It is arranged by subject, analogous to US Code. However, CFR Title numbers do not always match USC Title numbers. [e.g., 26 USC – Internal Revenue Code and 26 CFR – tax regulations; but 20 USC – Education and 34 CFR – education regulations.]
The first edition published in 1939 (for regulations in effect as of 6/1/38). Paperbound volumes published annually (since 1967). US Office of the Federal Register revises CFR on quarterly basis – January 1st – Titles 1-16; July 1st – Titles 28-41; April 1st – Titles 17-27 October 1st – Titles 42-50.

CFR Index and Finding Aids published annually. Not comprehensive, and usually refers to Parts, not Sections within Parts. Includes Parallel Table of Authorities and Rules.
