(Palace of the Commonwealth), Warsaw The National Library's history has origins in the 18th century (
Załuski Library) including items from the collections of
John III Sobieski which were obtained from his grand daughter
Maria Karolina Sobieska, Duchess of Bouillon. However, the Załuski collection was confiscated by troops of Russian tsarina
Catherine II in the aftermath of the
second Partition of Poland and sent to
Saint Petersburg, where the books formed the mass of the
Imperial Public Library on its formation in 1795. Parts of the collection were damaged or destroyed as they were mishandled while being removed from the library and transported to Russia, and many were stolen. It was opened in 1930 and initially had 200 thousand volumes. Its first Director General was Stefan Demby, succeeded in 1934 by
Stefan Vrtel-Wierczyński. The collections of the library were rapidly extended. For instance, in 1932 president Mościcki donated all of the books and manuscripts from the
Wilanów Palace Museum to the library, some 40 thousand volumes and 20 thousand pictures from the collection of
Stanisław Kostka Potocki. Initially the National Library lacked a seat of its own. Because of that, the collections had to be accommodated in several places. The main
reading room was located in the newly built library building of the
Warsaw School of Economics. In 1935 the
Potocki Palace in Warsaw became home for the special collections. A new, purpose-built building for the library was planned in what is now the
Mokotów Field, in a planned monumental "Government District". However, its construction was hampered by the outbreak of World War II. Before World War II, the library collections consisted of: • 6.5 million books and journals from 19th and 20th centuries • 3,000 early prints • 2,200
incunables • 52,000 manuscripts • maps, icons and music In 1940 the Nazi occupiers changed the National Library into Municipal Library of Warsaw and divided it as follows: • Department of Books for Germans (located in the
Warsaw University building) • Restricted Department, containing books that were not available to readers (located in the then main seat of the library—the School of Economics) • All special collections from various Warsaw offices and institutions (located in the
Krasiński Library) In 1944 the special collections were set ablaze by the Nazi occupiers as a part of repressions after the
Warsaw Uprising. This caused the destruction of 80,000 early printed books, including priceless 16th–18th century Polonica, 26,000 manuscripts, 2,500 incunables, 100,000 drawings and engravings, 50,000 pieces of sheet music and theatre materials. It is estimated that out of over six million volumes in Warsaw's major libraries in 1939, 3.6 million volumes were lost during World War II, a large part of them belonging to the National Library. == Collections ==
