All the writers present at the conference agreed to the utmost secrecy, and it was not until 1935 that the activities of the War Propaganda Bureau became known to the general public. Several of the men who attending the meeting agreed to write pamphlets and books that would promote the government's view of the situation. The bureau got commercial companies to print and publish the material. This included Hodder & Stoughton, Methuen, Oxford University Press, John Murray, Macmillan and Thomas Nelson.
