Treaties come under many different labels; agreements, convention, protocols, memoranda of understanding, modus vivendi, exchange of notes, or treaties. They can be bilateral or multilateral and they can be in force or awaiting ratification or adoption. Searches in law reviews and journals often reveal a wealth of information on citations, status, and parties to treaties.
Before beginning a search on treaties, the researcher should become familiar with the treaty making process and the special characteristics of treaty research. An excellent source to become familiar with treaty research is Treaty Research Basics, 89 Law Library Journal 407 (1997).
To understand how the treaty process works, the researcher should look at a treatise on the basics of treaty law, such as Modern Treaty Law and Practice.
The researcher can also find an excellent explanation of the ratification and implementation process for U.S. treaties at “National Treaty Law and Practice: United States” in National Treaty Law and Practice.
Another resource describing the process of treaty-making, including depositing a multilateral treaty with the United Nations Secretary-General, key events in the treaty process, and registering and filing a treaty is the Treaty Handbook from the United Nations, Office of Legal Affairs, Treaty Section.
