Travaux Preparatoires

Travaux Preparatoires, or “legislative history” of treaties, are preparatory documents concerning the negotiation and terms of the treaty. They may be difficult to find and are not published for every treaty. Major treaties may have volumes of records published. Use terms "travaux preparatoires" , "working papers," or "legislative history" with the name of the treaty to search for published volumes in discoverE, WorldCat, or UNBISNET.

Titles of published travaux may also be found on international library websitesPeace Palace LibraryEuropean Court of Human RightsEuropean Commission.

Travaux may be available on treaty websites as documents: see the Convention on the European Convention on Human Rights. Treaty secretariats and treaty websites may include meetings, reports, drafting documents, implementing legislation for member states. Find these with links from  Treaties in Force and in the treaty collections listed in the UN Audiovisual Library of International Law. Find history and drafts of major treaties in treatises on the treaty or on the subject matter of the treaty.
