Special Note: The entire collection is a deposit in the Archives of the Historical Records in Warsaw (Poland). http://baza.archiwa.gov.pl/sezam/sezam.php?l=pl&mode=show&zespoly_id=350 The Polish Institute of Arts and Sciences of America hold only the microfilms of this collection. However PIASA Archives does not have microfilm reader. The collection reflects a substantial part of the Count Potocki archives at Lancut Castle obtained by the Polish Institute of Arts and Sciences of America. Manorial records include documents and rescripts of inventories, charters, catasters, judicial decrees, testaments, and title deeds; personal papers including handwritten and signed letters, diaries, memoirs, and notebooks. These materials represent almost five hundred years of history, culture, and social life of one of the largest estates of pre- and post partitioned Poland. They reflect the feudal economic system of Poland that was the basis for the wealth of the magnates and for the prerogatives of the ruling families. Illustrious Polish families represented in these papers, correspondence and records are the Czartoryski, Lubomirski, Opalinski, Ossolinski, Ostrogski and Radziwill families and others.
