The Map Fonds contain over 3100 Topographical and Going Maps with Defence, Engineer, Flooding, and Geological Overprints, ranging from the 1910s to the 1990s. While the majority of the maps focus on Western Europe (France, Belgium, Germany, the Netherlands) during the Second World War, the collection also includes maps of North America, Italy, and China. The majority of the maps were created under GSGS (Geographical Section, General Staff, also known as MI 4), which operated under the Director of Military Operations and Intelligence in the British War Office during the Second World War. The GSGS collected data on foreign survey networks and provided training, supplied maps, and prepared survey data for the Allied forces.
