The Yearbook, which is published by the United Nations Department of Global Communications, stands as "the authoritative reference work on the annual activities and concerns of the Organization.
"[1] Fully indexed, the Yearbook also includes the texts of all major General Assembly, Security Council, and Economic and Social Council resolutions and decisions, placing them in a unique narrative context of United Nations consideration, deliberation and action.
The Yearbook contextualizes all resolutions, decisions, and other major activities of the principal organs of the United Nations and, on a selective basis, those of subsidiary bodies, and either reproduces or summarizes them in the appropriate chapter.
Written communications sent to the United Nations by the Member States and circulated as documents of the principal organs are summarized in selected cases under the relevant topics.
The Yearbook Twitter account @UNYearbook offers a historical perspective on current UN activities and concerns.
