"The Yearbook of the United Nations—published by the Department of Public Information—stands as the authoritative reference work on the activities and concerns of the Organization. Based on official UN documents, the Yearbook provides comprehensive coverage of political and security matters, human rights issues, economic and social questions, legal issues, and institutional, administrative and budgetary matters. Each of the sixty-five volumes of the Yearbook, dating back to the 1946–47 edition, includes the texts of all major General Assembly, Security Council and Economic and Social Council resolutions and decisions, and places them in a narrative context of UN consideration, deliberation and action."
