Page Explanation

Black's Law Dictionary defines treaty as "an international agreement concluded between two or more states in written form and governed by international law."

This page will assist you in locating treaties (in print and online), whether or not the U.S. is an involved party. It also gives you resources, in print and online, for learning more about treaties and how to find them.
