Explanatory Note

In order to facilitate reference to the United Nations Treaty Series, the Secretariat considers it desirable to publish a Cumulative Index (in English and French languages). This continues the practice of the League of Nations, which published a similar index to its Treaty Series. A volume of the United Nations Treaty Series Cumulative Index is issued for every fifty volumes of the United Nations Treaty Series (UNTS).

Each volume consists of two main sections, each preceded by an explanatory note.

In the first section, "Chronological Index", treaties and international agreements are listed in the order of the dates on which they were adopted, signed or opened for signature or accession.

The second section, "Alphabetical Index", refers to treaties and international agreements by parties and by subject-terms
