This collection of documents is a selection of official British government records pertaining to the creation of OPEC in 1960, and the activities of precursor and related bodies and events from 1947. The volumes cover OPEC's major meetings from 1960-1973, the reactions and evolving policy decisions on the part of British officials, diplomats and politicians at every level, as well as British interaction, co-operation and differences with the United States and the European Community, through the records of the Cabinet, the Foreign Office, the Ministry of Fuel and Power, Prime Minister's Office and the Treasury. British records are naturally dominated and informed by the relations with the major domestic oil companies, BP and Shell, through which many of the records tracing OPEC's activities were obtained.
