The intentions of the authors of the collection of jobbing prints and occasional publications in the Silesian Cabinet of the University Library in Wrocław The Silesian Cabinet, organised thanks to the efforts of Professor Antoni Knot and Zofia Gostomska, was the first branch of the University Library to open in Wrocław. Its creators came to the Lower Silesian capital in May 1945 to secure and develop research facilities for Polish scholars resettled there and for incoming students. The unique specialty of the Silesian Cabinet — collecting unconventional library material, mainly jobbing prints and occasional publications — could have resulted from a variety of factors, e.g. desire to expand the collection of Silesian items, including Polish ones, found in the German collections that were being reviewed at the time, or a need to preserve all printed sources of information that could be used to reconstruct the practical dimension and the scale of forced post-war migrations and their social consequences.The intentions of the authors of the collection of jobbing prints and occasional publications in the Silesian Cabinet of the University Library in Wrocław The Silesian Cabinet, organised thanks to the efforts of Professor Antoni Knot and Zofia Gostomska, was the first branch of the University Library to open in Wrocław.
