U.S. Treaties

Treaties are formal written agreements between countries. United States treaties are ratified by the president but require a two-thirds approval vote from the Senate. Executive agreements are similar to treaties and are made by the president but do not require the advice and consent of the Senate. Bilateral treaties involve two countries, while multilateral treaties involve three or more. 

This research guide focuses on agreements between nations. If you are looking for the text of statutes for foreign countries, try the Foreign Law Guide which is the online version of the book Foreign Law: Current Sources of Codes and Legislation (Reference K38 .R49 1989). Brief descriptions of foreign statutes can be found in the Martindale-Hubbell International Law Digest (Reserve).

To Check Status of a Treaty

Text of Treaties

  • United States Treaties and Other International Acts (TIAS) (1945- ) (Gov Docs S 9.10:) This series includes all treaties and international agreements during calendar year with United States as a party published in pamphlet form. They are prints of originals with marginal notes and footnotes. Although they are later bound as United States Treaties and Other International Agreements (UST), the library itself will now be binding the pamphlets in numerical order from TIAS 10727, since the GPO is no longer issuing UST to depository libraries in print.
     
  • United States Treaties and Other International Agreements (UST) (1950- ) (Gov Docs S 9.12:) This is the official permanent bound edition that has all of the United States Treaties and Other International Acts (TIAS) pamphlets. Because the GPO is now longer issuing UST to depository libraries in print, the library itself is now binding the TIAS pamphlets numerically by TIAS number beginning with TIAS 10727.
     
  • Hein's United States Treaties and Other International Agreements Current Microfiche Service (KAV) (Microform Cabinet 20) This is a relatively new service which is an attempt to be more up-to-date than the government sources for the text of treaties. It publishes the text of treaties within eight months of receipt by Congress. It has its own index which is located near the microform cabinet.
     
  • International Legal Materials (ILM) (print) (Periodicals K 9 .N868) This bimonthly periodical selectively publishes texts of treaties and is often the first place for a treaty to appear. In addition its "Recent Actions..." sections update the status of treaties.
  • Treaties and Other International Agreements of the United States of America 1776-1949 (Bevans) (Gov Docs S 9.12/2:) This set is valuable for retrospective treaty research. Volumes 1-4 are a chronological arrangement of multilateral treaties, while volumes 5-12 contain bilateral treaties arranged alphabetically by country. Volume 13 includes indexes by subject and country.
     
  • United Nations Treaty Series (UNTS) - Publishes treaties registered with the United Nations. Online at the subscription database http://untreaty.un.org/. Located in the library in the lower stacks (KZ172 .T74) and on microform.
     
  • Westlaw USTREATIES database (1778-) (Westlaw password required)
  • USTREATIES contains text of treaties to which the U.S. is a party, and Senate Treaty Documents (the text of the treaty and other documents transmitted from the President to the Senate).
