To determine when a particular section of the United States Code (U.S.C.) was added or amended, go to that particular section in the code. Immediately after the text of the law, note the list of public laws and citations to Statutes at Large in parentheses. These reference all of the public laws that have created or amended this particular section of the Code. The later "Amendments" section give a more detailed listing of when particular language was added to the section with references to their public law number.
The West unofficial United States Code Annotated (U.S.C.A.) also includes that list of public laws creating or amending a section as well as a more detailed "Historical and Statutory Notes" section that assists the reader in discerning when particular language was added to a public law. It also includes references to committee reports that appear in the West publication United States Code Congressional and Administrative News (U.S.C.C.A.N.).
