Historical Treaties

Introduction

This guide is intended to be a supplement to the Law Library’s comprehensive Guide to Treaty Research. The advice contained in that guide should also be observed when researching older treaties. While pre-1949 treaties used to be very difficult to find in electronic format, many of the treaty collections and finding aids described in this guide are now available from HeinOnline's World Treaty Library or U.S. Treaties and Agreements Library. Where electronic versions are not available or preferred, the Diamond Law Library's vast print historical treaty collection can be consulted.

Finding Aids

Getting Starting with Treaty Research

Finding the official full-text sources for a treaty can be a tricky endeavor. The best way to start your search for a treaty is to consult one of the following indexes or finding aids to find the relevant citation for your treaty.
