 All the writers who attended agreed to maintain the utmost secrecy, and it was not until 1935 that the activities of the War Propaganda Bureau became public knowledge.Several of the writers agreed to write pamphlets and books that would promote the government's point of view; these were printed and published by such well-known publishers as Hodder & Stoughton, Methuen, Oxford University Press, John Murray, Macmillan and Thomas Nelson.The War Propaganda Bureau went on to publish over 1,160 pamphlets during the war.
