Treaty Research

This guide describes resources and methods for locating and updating treaties of the United States and other countries.

U.S. Treaties & Agreements

Table of Contents


Overview

U.S. law makes a clear distinction between treaties, which require the advice and consent of the Senate before they may enter into force, and executive agreements, which do not.  Both treaties and executive agreements are included in indexes and in official and unofficial full-text sources.  Official sources, published by the U.S. government, are preferred for citation purposes.
 
Use the links in the table of contents above to guide you through the research process.  Alternatively, you may wish to utilize HeinOnline's U.S. Treaties and Agreements Library, which allows you to search across multiple indexes for treaties and agreements that are currently in force, for those that are no longer in force, and for those that have not yet entered into force.
