Principal UN Organs and Their Functions

General Assembly. New York. Includes representatives of all member states. Annual sessions of the plenary meetings are held from September until December. Special and emergency sessions may also be convened. There are six main committees of the General Assembly. These are:

  • First Committee (disarmament and international security)
  • Second Committee (economic and financial)
  • Third Committee (social, humanitarian and cultural)
  • Fourth Committee (special political and decolonization)
  • Fifth Committee (administrative and budgetary)
  • Sixth Committee (legal)

In addition, there are the standing and procedural committees and other subsidiary organs of the General Assembly.

Security Council. New York. Composed of five permanent (U.S., U.K., Russia, China and France) and ten non-permanent members elected by the General Assembly for two-year terms. Primary responsibility is maintenance of international peace and security. Functions continuously and meets whenever called.

Economic and Social Council. New York and Geneva. Composed of 54 members elected by the General Assembly for three-year terms. It is responsible for the economic and social activities of the United Nations. It conducts two regular sessions and an organizational session each year.

Trusteeship Council. Composed of the permanent Security Council members. In November 1994 the last of the original eleven Trust Territories was removed from its administrative authority. Having completed its original mandate, the Council will meet in the future only as need arises.

International Court of Justice. The Hague. All members are automatically parties to the Court's statute and non-members may become parties. The court has 15 independent judges of different nationalities, elected for nine-year terms by the Security Council and the General Assembly. (Most ICJ publications are found in the Law Library)

Secretariat. The Secretariat services the other organs of the United Nations and administers the programs and policies laid down by them. It is headed by the Secretary-General who is appointed by the General Assembly. It functions continually and has many units.

Subsidiary UN Bodies and Their Functions

As a general rule, publications from these organizations are not part of the United Nations depository program. However, the University of Iowa Libraries does selectively purchase titles from these organizations based on cost, availability and meeting the goals of the Government Publications Collection plan. If there is a title not held by the Libraries, individuals may request that it be purchased or initiate an interlibrary loan request.
