General treaty sources

United Nations Treaty Collection

  1. United Nations Treaty Series. The treaties are published by year of registration, which is often later than the dates on which they were signed or came into force.
  2. Multilateral Treaties Deposited with the Secretary-General. This gives the current status (signatures, ratifications, reservations etc.) of over 500 treaties, as well as the citation to the current printed version.

European and Council of Europe Treaty Series - known as European Treaty Series until 2003 and as Council of Europe Treaty Series from 2004 onwards.

See the research guide from the Institute of Advanced Studies library.

European Union treaties - from Eur-Lex

Major treaty portals and sources

  • EISIL (Electronic Information System for International Law) - "an open database of authenticated primary and other materials across the breadth of international law".
  • Minnesota Human Rights Library - "more than sixty thousand core human rights documents, including several hundred human rights treaties and other primary international human rights instruments."
  • The Avalon Project from Yale University's Lillian Goldman Law Library - "digital documents relevant to the fields of Law, History, Economics, Politics, Diplomacy and Government".
  • International Legal Materials (ILM) - Published by the American Society of International Law since 1962. It contains current international and United States documentation on international law, including treaties, cases of international interest and other documents of current relevance.
