Updating the e-CFR, Lexis CFR, and Westlaw CFR for Amendments
Online sources are usually more current than the official print sources. Be sure and check the currency of your online CFR source. The differing dates may mean that you can skip traditional updating steps. For example, you likely will be able to skip checking the Monthly List of CFR Sections Affected and just look at the "Reader Aids" section," CFR Sections Affected during [month]" of the latest issue of the Federal Register.
Example:
The eCFR was last updated February 14, 2023. Today is February 16, 2023. Look at the "CFR Parts Affected during February in the "Reader Aids" section of the February 16, 2023 issue of the Federal Register.

Updating the Official CFR (in print or online)
- Note date of revision on the cover of the CFR volume that contains your regulation. Remember that the CFR is updated yearly on a quarterly schedule.
- Consult the LSA -- List of CFR Sections Affected.
- If the revision date of the volume of the CFR used is less than one year out-of-date, use only the most recent issue of the LSA (check the coverage statement on the title page of the LSA to make sure there are no gaps in coverage).
- If the revision date of the CFR volume is more than one year out-of-date, you may need to use two issues of the LSA: the annual issue for that title and the most recent issue.
- If the regulation has been updated, flip to the "Table of Federal Register Issue Pages and Dates," located at the back of the LSA. Look up the page number reference given in the LSA to determine which issue of the Federal Register contains the revisions or changes.
- Consult the Federal Register.
- Look at the issue for the last day of each month since the last LSA pamphlet. There will be a section in the back under “Reader Aids” called "CFR Parts Affected during [month]." Also check the last day of the current month.
