In accordance with Article 102 of the Charter and the relevant General Assembly Resolutions, every treaty and international agreement registered or filed and recorded with the Secretariat is published in the United Nations Treaty Series. At present, the collection includes about 30, 000 treaties reproduced in their authentic languages, together with translations into English and French, as necessary. The Treaty Series also provides details about their subsequent history. Comprehensive Indices covering 50-volume-lots are published separately.
