In addition to complete coverage of Thuringia with geological maps at the scale of 1:25,000 (GK25) and extensive coverage of neighbouring areas of Germany at various scales (GK 1:25,000, GÜK 1:200,000), the collection also hosts numerous map series from all across Europe and other continents. The collection also focuses on the Alps, Eastern Europe and especially the Balkan Peninsula (former Yugoslavia, Albania, Bulgaria, Greece). For example, there is a complete set of geological maps of all republics of former Yugoslavia at a scale of 1:100,000.
The map collection also contains numerous original reports and maps of geological expeditions to non-European areas from the 1960-80s, which were produced for the former Department of Praktische Geologie Jena (originally a department of the Instituts für Geotektonik Berlin, from 1969 part of the Zentralinstituts für die Physik der Erde), as well as Berichte der Akademie der Wissenschaften zu Berlin/der DDR (reports of the Academy of Sciences in Berlin/GDR).
Since 2020 the map collection is part of the collections of the Friedrich-Schiller University JenaExternal link.
