1. Use the Code of Federal Regulations Index volume to find the appropriate title(s) and part(s). Note the date of the CFR volume containing the regulations.
2. Browse the latest issue of the List of Sections Affected (LSA) for references to the CFR title(s) and part(s) identified above. The numbers are the pages in the Federal Register which contain changes to the particular CFR title(s) and part(s).
3. Update that information by using the "CFR Parts Affected" table in the "Reader Aids" section of the most recent issue of the Federal Register. (This table covers only the current month. If you need to check changes made in earlier months, go to the last Federal Register issued for that month).
