Published in conjunction with The Imperial War Museum, this CD Rom is the second in this series, the first being Military Operations France and Belgium: 1914-1918 Maps on CD-ROM. Full details of both CD Roms can be found at www.official-history-ww1.com 

The Official Historians had the benefit of various collections of maps at the start of their work in 1920. Although, following the Armistice, many records were pulped or burned in France, the annotated maps were untouched. Many 1914-18 records were later destroyed by enemy bombing in 1940, but the Official Historians also used information supplied after 1918 by their former allies and enemies. 

Recent reprints of the Official Histories have included sketches bound into the text volumes, but have excluded the maps in pockets and in map-cases which have never been reprinted since the original publication of the series. Naval & Military Press now present these maps on this new CD-ROM, which covers:

Military Operations, Italy 1915 -1919 (5)
Military Operations, Egypt & Palestine Vol I (15) & II (24)
Gallipoli Maps & Appendices 2 Parts (11)
Mesopotamia Campaign 1914-1918 Vols I-IV (43)
Military Operations, Macedonia 2 Parts (24)
Campaign in German South West Africa 1914-1915 (16)
Military Operations, Togoland and the Cameroons (15)

The items are very diverse, including small-scale wide area maps, fully contoured and coloured larger scale sheets, highly specific plans such at that of the Battle of Kut which covers an area less than 10 miles wide, and even a secret German battle-plan sketch, found on the body of a dead officer.

They all appear to show army, not naval or air operations, but provide a detailed context for all events of the period. There is no gazetteer or index of place names on the disc, so some knowledge is required to make the best use of this resource.
The viewing software offers a variety of on-screen navigation and magnification tools, and it is easy to print out any map.
