Treaties and International Agreements

Guide to print and electronic resources for finding bilateral and multilateral treaties.

Treaties and International Agreements

Article 2, Section 1(a) to the Vienna Convention on the Law of Treaties, which has been widely accepted as the instrument governing the law of treaties since its adoption by the International Law Commission in 1969, defines a treaty as such: 

'Treaty' means an international agreement concluded between States in written form and governed by international law, whether embodied in a single instrument or in two or more related instruments and whatever its particular designation....

Treaties one of the main sources of international law. Indeed, conducting international legal research almost invariably involves locating a treaty at some point, whether bilateral or multilateral. Bilateral treaties are those treaties concluded between two states or organizations, and multilateral are those concluded between more than two states or organizations. Treaties are one type of international agreement, and can also be called things such as agreement, settlement, pact, accord, protocol, compact, convention, or covenant, etc. 

The purpose of this research guide is to identify relevant print and electronic resources for locating treaties and international agreements. The guide lists useful treatises on the law of treaties, print indexes necessary for locating official texts of treaties, and databases offering full-text access to thousands of international agreements.
