Each title of the Code of Federal Regulations is revised once a year and contains the regulations in force at the time of publication. The schedule for publication is:
|Titles 1-16||January 1|
|Titles 17-27||April 1|
|Titles 28-41||July 1|
|Titles 42-50||October 1|
The revision schedule for unofficial versions of the C.F.R. is faster than the quarterly revision schedule of the official C.F.R. To update regulations, you will need to determine how current the regulation is in the C.F.R. source that you are using and then search the Federal Register for information on your regulation from that currency date to the present.
On e-CFR, the currency date is above the text of the regulation. On Westlaw, click on the “Currentness” link above the text of the regulation in the C.F.R. to see the currency date. On Lexis, find the currency date in the preliminary information above the text of the regulation in the C.F.R.
