Utrecht University Library manages an appealing collection of cartographic documents. The majority of the most recent maps, charts and atlases are kept in the Map Room on the sixth floor of Utrecht University Library Uithof. Older documents and those that are consulted less frequently are stored in the depositories and can be requested using the Worldcat-catalogue. The items cannot be borrowed, but can be consulted in the reading room.
More information about searching and consulting of maps in the Libguide Maps and atlases (still in Dutch).
