During the Second World War, the Ministry of Information (MOI; MofI) was the British Government's organ for disseminating news and information to the public. It operated in many fields, principally being responsible for information policy and propaganda in Allied and neutral countries. It published many books through His Majesty's Stationery Office, some relating the story of the progress of the war, such as "Roof over Britain", which dealt with the air defence of the United Kingdom and "Target Germany", which told of the US 8th AAF. Other subjects included HMS Ark Royal, the Mediterranean Fleet and the Eighth Army.
As writing and art were not reserved occupations, writers and artists were liable to call-up into the armed forces. The MOI could therefore call upon a broad base of talent to produce their books. These tended not to credit individual writers but were inscribed:
"PREPARED FOR THE ADMIRALTY (or WAR OFFICE or AIR MINISTRY as applicable) BY THE MINISTRY OF INFORMATION"
