The United States Treaties collection includes the United States Treaty Series (1795-1945) and United States Treaties and Other International Agreements or TIAS (1950-1984). This collection includes treaties to which the United States is or was a party in the agreement.

The U.S. Department of State makes available United States treaties after 1984.
