FCO historians are responsible for editing Documents on British Policy Overseas (DBPO) and for overseeing the publication of FCO Internal Histories.
DBPO comprises three series of diplomatic documents, focusing on major themes in foreign policy since 1945, and drawn principally from the records of the Foreign and Commonwealth Office. The latest volumes, published in Series III, are composed almost wholly of documents from within the thirty-year ‘closed period’, which would otherwise be unavailable to the public.
Since the early 1960s, several Internal Histories have been prepared by former or serving officers, the majority of which concentrated upon international developments and negotiations in which the UK has been directly involved. These were initially intended for use within the FCO, but some of the more substantial among them, studies that offer fresh insights into British diplomacy, are now being declassified for publication.
