A guide to researching treaties and international agreements.

Identifying Current Treaties

United Nations Treaty Series (UNTS)

Under the UN Charter all member nations are required to register their treaties, both bilateral and multilateral, with the United Nations. In practice many nations do not submit their treaties, however, this is still the most complete source of treaties available. The UNTS has a Cumulative Index which began with the first hundred volumes and is now issued every fifty volumes.
