  • See the code index for some treaty titles or subjects under Convention, Treaty, or International Agreement.
  • In USCA on Westlaw, search the USCA Index for treaty references, search treaty titles in Popular Names with "implementation act" and the treaty name, and search the code text and notes for references to the treaty.
  • In USCS volumes, use the International Agreements volume to find headings for Implementing Legislation with major treaties.  Other treaties may be referenced in the annotations for related or implementing legislation. In Lexis, find implementing and related legislation with USCS International Conventions, or search in the USCS by treaty name for related legislation.
