Finding Aids

The archives are arranged as series within the United Nations office or agency that created them. The creating agency could be a United Nations department, mission, tribunal or any other United Nations functional unit. The United Nations archives cover these broad areas: Predecessor Organisations, Secretaries-General, Secretariat Departments and Field Operations.

Finding aids can be used to gain an in-depth knowledge of a specific office, field operation, or person. They contain the same information as the search engine, presented in a different format.

Archives of Secretariat Departments

Departmental records are split into two organizational systems:

  • Registry Files: the first records registry was set up during the London period of the Preparatory Commission of the United Nations (between 21 November 1945 and 31 January 1946) and patterned after that of the British Foreign Office. The system was discontinued in 1979, however, the fonds include records dating up to 1983. The registry system was succeeded by decentralized recordkeeping by departments in consultation with the Archives Section's records management programme.
  • Non-registry records: arranged according to the departmental organization of the Secretariat (from 1946 to present), include the archives of: Office of the Secretary-General, Office of Legal Affairs, Department of Economic and Social Affairs, Office of Public Information, Department of Trusteeship and Non-Self Governing Territories, Department of Political and Security Council Affairs, and many others.
