Not everything published by the OAS is considered an official document. Its official documents are only those published by its General Secretariat for the organization’s deliberative organs that are then classified as part of the Official Records Series.
Included: Minutes of the Council (1948-1969) and Permanent Council (1970-present), resolutions of the General Assembly, committee reports, proceedings of the Inter-American conferences and meetings, final acts of specialized conferences, meeting agendas, the Annual Report of the Secretary General, statutes and regulations.
To a sense of what may be considered an official document, please see the OAS organizational structure.
Not included: confidential documents, promotional materials, reports, monographs, bulletins, and other publications outside of the categories described above.
