The Routledge Atlas of the First World War 
Martin Gilbert
Routledge
This atlas offers a definitive visual history of World War I. In 164 finely detailed, easy-to-read maps, it covers the origins of the war, the quarrels of the great European powers and the mobilization of 1914, plus the major battles and all the individual campaigns including the war at sea and in the air–putting them in the wider context of strategy. Beyond its thorough and precise military coverage, the atlas also explores the diplomatic, economic, and social aspects of the conflict. Many of the maps–such as a map of German food riots in 1916, a state-by-state map of opposition to the war in the United States in April, 1917–have put together normally scattered and diverse information with exceptional clarity.
