International Treaties (SAIS)

Finding Treaties

Treaties are the end result of negotiations between two or more parties. There is no single comprehensive index or collection of treaties available in print or online. It may be necessary to check several sources to locate a treaty and there may be a delay of many years before the official text is published.
