In 1951, the communist authorities of People's Poland established the Polish Academy of Sciences. In its early days, this institution was in fact an instrument of control over scientific life in Poland, taking over a number of scientific societies and foundations. The National Ossolinski Institute was not spared. From 1953, two independent structures operated within the Polish Academy of Sciences: The Ossolinski Institute - Library and the Ossolinski Institute - Publishing House. The adjective 'national' disappeared from the official names.
