Official Documents System of the United NationsThe United Nations Official Documents System (ODs) is the electronic repository for official documents published by the United Nations. The full text of documents is accessible in PDF format in all official languages of the United Nations--Arabic, Chinese, English, French, Russian and Spanish. Documents are stored in two databases: UN documentation with comprehensive coverage beginning in 1993 and selected earlier coverage, and UN Resolutions, which includes the official records version of resolutions of the General Assembly, Security Council, Economic and Social Council and Trusteeship Council since 1946. Information on how to search for documents is available from extensive HELP files or by clicking on any of the field names on the search forms. The Useful links page provides access to essential tools that can be helpful in searching for UN documentation.
