The article characterises the collection of 19th century prints held in the collection of the Emilia Sukertowa-Biedrawina Voivodeship Public Library in Olsztyn. The material provides a source representing the current numerical and chronological status of the book collection. The author discusses the provenance of the library's collection from the perspective of provenance research conducted since 2022, as well as the history of the institution in the context of the formation of the post-war libraries in Olsztyn and the fate of the collections abandoned by the Germans. The aim of the paper is to provide a preliminary analysis of the content and publication of the collection, including the language of the publications, the places of publication and the thematic range of the prints, with a particular emphasis on regional (East Prussian) themes, as well as an overview of the current state of preservation of the collection in light of the conservation work carried out in recent years. Looking at these issues will allow the collection of historical books of the Voivodeship Library in Olsztyn to be included in research into the history of librarianship in Warmia and Mazury, as well as to extend the conservation care.
