Administrative Law: Updating & Tracking Federal Regs
Traditional updating method (alerts you to changes affecting a specific section):
Begin by locating the desired regulation in the most recently revised edition of the C.F.R.
Then consult the most recent monthly edition of the List of CFR Sections Affected (LSA).
The LSA is a monthly publication listing each C.F.R. section that has been impacted by changes published in the Federal Register since the C.F.R. volume's last revision date. It is a cumulative publication. Therefore, you only need to check the most recent issue to determine whether any changes to a regulation have taken place since the last C.F.R. was published.
Go to the most recent issue of the Federal Register for each month not covered by the LSA. At the back of each issue is a cumulative list called "CFR Parts Affected During [month]." This listing updates the most recent edition of the LSA. You can also update your research using the LSA online at govinfo.gov.
Expedited updating method (skips the LSA and alerts you to changes affecting an entire part):
From govinfo.gov go to CFR Parts Affected from the Federal Register.
Select the Date range since the most recent CFR for your provision (Date is after: Jan. 1, April 1, July 1, or Oct. 1, 202x). Submit.
Open the title and part to check for changes.
The following video demonstrates the expedited method.
What to do if the C.F.R. section no longer exists.
Look in the LSA to see if it has been redesignated.
Look in the back of the appropriate C.F.R. volume for a Redesignation Table.
Look in the back of the appropriate C.F.R. volume for an LSA table by year. This will reflect any changes that have occurred since 2001. For the period before January 1, 2001, see the compiled List of CFR Sections Affected volumes that are shelved before the current C.F.R. on the first floor, shelf 9 (KF70).
Web Resources for Updating Regulations
Because the official version of the C.F.R. is only updated once each year, updating your C.F.R. research to ensure you have current information is essential.
The fastest and most cost-effective way to update regulations is to use govinfo.gov. The same quarterly publication schedule for the printed C.F.R. volumes is followed on this site and it is considered an official source of the C.F.R. To update your regulation, note the date when the current C.F.R. volume containing your section was revised (published). Then consult the next two items listed in this box to complete your updating.
Since the LSA is a monthly publication, its coverage stops at the end of the previous month. To check for more recent changes, use the "CFR Parts Affected from the Federal Register" updating tool and enter a date range to ensure your research is current through today's date.
Reginfo.gov displays regulatory actions and information collections currently at OIRA for review. Various options for searching the unified agenda are under that tab. (See explanation of unified agenda.) The regulatory review tab includes access to a dashboard that provides information about regulatory actions currently under review.
