Looking for a 19th century treaty between the United States and China? Or perhaps an Obscure treaty between Great Britain and Prussia in the late 18th Century? You may want to check out HeinOnline's World Treaty Library. If there is such a thing as "One Stop Shopping" for treaty research, this vast repository of U.S. and Non. U.S treaties dating from from 1648 to the present, may be it. 

Major collections include Hein’s U.S. Treaty Index, United Nations Treaty Series, the League of Nations Treaty Series, and a number of specialized treaty collections (e.g. Rohn’s World Treaty Index and Martens’ Treaties) that contain current and historical treaties. The database also boasts a wide array of diplomatic documents, articles, and bibliographies related to treaty research.

The World Treaty Library can be searched by keyword, title, countries, full text, treaty number, and by a number of other fields.

For help searching, see HeinOnline's Quick Reference Guide (PDF).

For questions or for more help on searching this database, contact Sunil Rao, Foreign and International Law Librarian.
