Documents on British Policy Overseas is a fully searchable collection of primary source documents from Britain's Foreign and Commonwealth Office, shedding light on diplomatic history throughout the twentieth century. It is based on three distinct print series which form a record of British peacetime diplomacy since the end of the nineteenth century:
- British Documents on the Origins of the War 1898-1914,
- Documents on British Foreign Policy 1918-1939 and
- Documents on British Policy Overseas.
Documents are selected and edited by the official historians of the FCO, with many documents specifically declassified for inclusion. The Documents on British Policy Overseas database is produced in collaboration between ProQuest and the Foreign and Commonwealth Office.
