The United Nations Treaty Series (UNTS) is a publication produced by the Secretariat of the United Nations containing all treaties and international agreements registered or filed and recorded by the Secretariat since 1945, pursuant to Article 102 of the Charter.

Lexis and Westlaw both offer databases for retrieving the full texts of treaties and other international agreements to which the U.S. is a party. If you have a citation to an official source, such as T.I.A.S. or U.S.T., you can use that citation to retrieve the full text of the treaty on Lexis and Westlaw.

You can find a specific treaty registered with the Secretariat by going to the United Nations Treaty Series page in the Registration and Publication section of this website.
