Treaty Research

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

Official Full-Text Sources for U.S. Treaties

Once you have a citation, you can use it to retrieve the full text of the treaty or agreement from an official or an unofficial source.  Official sources are preferred for Bluebook citation purposes.  The following table lists official sources for U.S. treaties and/or executive agreements, along with information on how to access them.

Title and Description Citation Dates of Coverage Print/Microform Holdings Online Access
Senate Treaty Documents (1981-present)
Senate Executive Documents (1789-1980)
Treaties submitted to the Senate for ratification are first published as Senate Treaty Documents (formerly known as Senate Executive Documents).  In addition to the full text of the treaty, you will find letters of transmittal from the president and the secretary of state, along with other supporting or explanatory documentation.  Senate Treaty Documents are also useful for locating the texts of recently ratified treaties before they are published in other official sources.
