For correspondence and papers of the Secretariat of the CID during the period 1902-1918 see CAB 17
Selected files from the series which started from January 1966 are in CAB 164
Separated Material:
Some pieces in this class originally contained NATO documents, which were extracted and replaced with dummy cards when the pieces were transferred to the PRO. The dummy cards state that the extracted documents are retained by the Cabinet Office. With the agreement of the PRO, these extracted NATO documents were destroyed by the Cabinet Office in May 2001. Researchers wishing to seek access to extracted documents should apply to the NATO Archives in Brussels.
