Finding UN Documents

Finding UN documents is not always easy or straightforward! The UN's Dag Hammarskjöld Library has produced an extremely helpful research guide on UN System documentation. For each of the programmes, funds, specialized agencies and regional commissions, the guide provides information about:

  • Founding documents
  • Governing body’s pattern of documentation
  • Flagship publications
  • Information resources, databases
  • Chief Administrative Officers

The UN website includes the following:

  • The Charter of the United Nations
  • The UN and the Rule of Law - the principle that everyone – from the individual right up to the State itself – is accountable to laws that are publicly promulgated, equally enforced and independently adjudicated, is a fundamental concept which drives much of the United Nations work.
  • UN Rule of Law Documents
  • Official Document Centre includes all types of official United Nations documentation, beginning in 1993. Older UN documents are being constantly added. The ODS also provides access to the resolutions of the General Assembly, Security Council, Economic and Social Council and the Trusteeship Council from 1946 onwards.
  • General Assembly and Security Council - 'landmark' documents
  • Year book of the UN - full text, free and complete collection 1946 to date (note: publication is several years behind - for example the 2007 Yearbook was published in 2011). The Yearbook is the principal reference work of the United Nations and provides a detailed overview of the Organization's activities. Each Yearbook is fully indexed and includes all major General Assembly, Security Council and Economic and Social Council resolutions.
  • The Journal of the United Nations - full text from 2003+. The Journal contains the daily programme of meetings at Headquarters of the General Assembly, Security Council, Economic and Social Council and other bodies scheduled to take place on a given day, as well as identifies the symbols of major documents to be considered at the meetings -- even when the documents may not yet have been officially released. It also summarises treaty actions which have been undertaken at the previous day by States in respect of multilateral treaties deposited with the Secretary-General.
