"This comprehensive handbook designed for the general public explains the structure of the United Nations, how the Organization works, the main issues it addresses and its importance for people everywhere. In addition to setting out the various roles played by principle UN organs and related organizations, Basic Facts about the United Nations documents the Organization’s contributions to international peace and security, economic and social development, human rights, humanitarian action, international law and decolonization. Appendices contain current data on UN membership and peacekeeping operations, as well as contact information for UN information centres, services and offices. This latest edition has been revised to take account of significant developments in the world and the Organization itself since 2011."

"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. The latest edition, the Yearbook of the United Nations, 2012 (Vol. 66), was published in March 2017." See "About" section for more detail" https://unyearbook.un.org/content/about-yearbook
