<P> The History of the Second World War is the official history of the British contribution to the Second World War and was published by Her Majesty's Stationery Office (HMSO). The immense project was sub-divided into areas to ease publication, United Kingdom Military Series, the United Kingdom Civil Series for the civilian war effort; the Foreign Policy series, the Intelligence series and the Medical series are eponymous . Other volumes not under the aegis of the series but published by HMSO may be read as adjuncts, covering matters not considered in great detail or at all, in one case, in the main series . Further volumes, published after the privatisation of HMSO or in the series about the Special Operations Executive, are also useful . </P> <P> The volumes were intended to be read individually, rather than in series, which led to some overlapping but in their introductions to their parts of the series, Sir Keith Hancock and Sir James Butler wrote that this was to obviate a need to read more volumes than cover the part of the war effort being studied; Hancock edited the Civil Series and Butler the Military Series . The first volume appeared in 1949 and the last in 1993, with a revised edition of one volume appearing in 2004 . An unorthodox decision was to cover the conflict from a theatre of operations point of view rather than by service, to acknowledge that military operations were intimately linked . </P>
