Bloomsbury has purchased the backlist of The National Archives Publishing programme, and entered into an agreement to co-publish a range of forthcoming titles.

The National Archives of the United Kingdom, in Kew, holds more than 1,000 years of government files from Foreign and Home Office records to colonial and military documents, with more than 80 million digitised records.
