Date: 1915-1971

From 1930-1936 registration was purely numerical, blocks of numbers being assigned in advance to different countries or subject; e.g. 4000 onwards to Constitutional Affairs, Imperial Conferences etc., 6000 onwards to Foreign Affairs, League of Nations etc.

On 1 January 1937 a modified form of the 1930-1936 registration system was introduced. From that date papers were registered in groups according to their subject matter, each group being indicated by a letter. The prefix letters were allocated as follows:-

  • A. Aviation (Civil)
  • C. Constitutional (including Imperial Conference, Coronation, Petitions to His Majesty).
  • D. Defence (including Disarmament, Naval Conferences, Naval, Military and Air Force matters).
  • E. Establishment (including Representatives in the Dominions of His Majesty's Government in the United Kingdom.)
  • F. Foreign Affairs (including League of Nations, Non-Economic Treaties, Drugs).
  • G. Geographical.
  • H. Honours and Ceremonial (including Naval, Military and Air Force ceremonial matters).
  • K. Consular and Diplomatic.
  • M. Migration.
  • N. Newfoundland.
  • O. Inter-Imperial Trade Questions (including Research Bureaux and Dominion Financial questions).
  • P. Passport and Nationality (including Aliens and Naturalisation cases).
  • Q. Cables, Wireless and Broadcasting.
  • R. Southern Rhodesia.
  • S. Shipping.
  • T. International Trade Questions.

  • X. Irish Free State
  • Y. Basutoland, Bechuanaland Protectorate and Swaziland.
  • Z. Miscellaneous (including Copyright and Patents, Medical, Education, International Conferences and Exhibitions, Maintenance Orders, Repatriation and Deportation questions).
Groups were subdivided into various subordinate subjects by means of numbers (starting from 1) placed after the appropriate letter.

This procedure was further modified on 1 January 1947 when each subject group was renumbered from 2000. The same prefix letters were retained and the following list indicates the subject matter allocated to each file series:-

  • A. Aviation and air passages
  • B. Naval, Military and Air. (Personnel and Misc.)
  • C. Constitutional
  • D. Defence questions of policy etc.
