World Treaties

Sources and finding guides for treaties to which the U.S. may not be a party.

Introduction

This guide lists print and online resources for researching treaties to which the United States is unlikely to be a party. A separate research guide on U.S. Treaties and International Agreements lists resources for researching treaties to which the United States is a party. There are two different research guides because different indices, finding guides, and databases are useful to find treaty text and treaty status depending upon whether or not the U.S. is a party. If you are in doubt about whether the United States is a party to a particular treaty, use the indices and finding guides listed in the research guide for U.S. Treaties and International Agreements first.

If you have questions about treaty research -- U.S. or not, current or historical -- Heafey Research Librarians will be happy to help: 408 554-4452; lawref@scu.edu.
