Działalność katowickiej Zbiornicy Księgozbiorów Zabezpieczonych na Górnym i Dolnym Śląsku w latach 1947-1953

The article concerns the activities of the Storehouse of Secured Libraries of Katowice. Since 1950 it was responsible for liquidation of other storehouses of that kind in Poland, especially for “assault operation in Wrocław”. Such term was used by Franciszek Szymiczek, the director of the ZKZ when describing the burdensome nature of liquidation activities. This resulted in the grinding of majority of over 800,000 books and journals hitherto stored in the ZKZ of Wrocław and the Wrocław University Library in 1951. The article contains previously unknown information about the provenance of the stored books and the methods of their division. The style and results of actions undertaken by the ZKZ were highly dependent on external factors, political and industrial, resulting from the implementation of the 6-year plan, as well as logistic capabilities and capacities of hired personnel.
