Map collection
The map collection can be used through the library service. Information on holdings and usage can be found below.
Map holdings
There are some 100,000 maps in the map collection, which includes both map series and individual maps. The library holds all official topographical map series from the TK25 to the IWK for the territory of the former West Germany plus a series of special maps and themed maps for a number of regions (such as the Rhineland). These themed maps also include extensive holdings of geological maps with their explanatory reports, particularly for the territory of the former West Germany. You can search for maps in the same way as other works via Bonnus.
