The collection consists mostly of pre-war publications from the collection of Wojewódzka Biblioteka Publiczna in Olsztyn - mainly from the resources of the reading room. Some of the objects are related to Warmia and Mazury. The presented books are literary works (novels, poetry), but also guides, historiography, and bibliographies. An extremely important part of the collection is the "Bibliography of Warmia and Mazury" for the years 1945-1998.
