Berlin State Library

In the early period, the fortunes of the State Library rose and fell on royal whims. In 1658 Frederick William, Elector of Brandenburg decreed that his private books be organized, cataloged and made available to the public. His library opened in 1661 at Cölln as the "Library of the Elector" (German: Churfürstliche Bibliothek zu Cölln an der Spree). In 1699, Frederick I more than doubled the collection, extended opening hours and introduced the first Prussian legal deposit law. In 1701 it was renamed the "Royal Library" (German: Königliche Bibliothek) upon Frederick I's accession as first King of Prussia. Frederick William I then cancelled the acquisition budget in 1722 and gave away the valuable scientific collection to the Prussian Academy of Sciences in 1735. Frederick the Great also cared little for the library at first, preferring instead his own literature in the French language. However, in 1770 he granted the library substantial assets and it made several important acquisitions. To avoid the problems caused by its dependence on the crown, Frederick the Great also granted the library considerable autonomy.[7]

Old Royal Library on Bebelplatz

With new resources and authority, construction began on a Royal Library building on the Bebelplatz in the center of Berlin. Built between 1775 and 1785 by Georg Christian Unger to plans by Joseph Emanuel Fischer von Erlach, it was nicknamed the Kommode (Chest of drawers) after its Neo Baroque design. The collection then underwent nearly continuous improvement and expansion. By 1905 it had become the largest and most influential repository of materials in the German language, and at 1.2 million books one of the largest libraries in the world.[8] The Bebelplatz building housed the library until 1914, when the headquarters moved into new, even larger premises on the Unter den Linden: the climax of the library's development before the First World War. Today the old Royal building houses the Faculty of Law of Humboldt University.

At the founding of the Weimar Republic the library was renamed the "Prussian State Library" (German: Preußische Staatsbibliothek - Preussischer Staatsbibliothek). After 1919, economic effects of war and inflation on the library were mitigated through the active support of the Emergency Association of German Sciences (after 1930, the German Research Foundation).

Book burning on the Bebelplatz, May 1933.

The Nazi period severely damaged the institution through political intimidation, employee dismissals, restrictions on foreign acquisitions and the effects of World War II. On 10 May 1933 a book burning ceremony was held at the Bebelplatz by members of the Deutsche Studentenschaft, the National Socialist German Students' League, Sturmabteilung "brownshirts" and Hitler Youth groups at the instigation of the Propaganda Minister, Joseph Goebbels. The Nazis burned over 20,000 books - mostly from the neighboring University, not the State library itself – including works by Thomas Mann, Erich Maria Remarque, Heinrich Heine, Karl Marx and many others. Today a glass plate set into the Bebelplatz, giving a view of empty bookcases, commemorates the event. After an Allied bomb hit the Unter den Linden building in 1941, the various holdings (now some 3 million volumes and over 7,400 incunabula) were evacuated to 30 monasteries, castles and abandoned mines around Germany. By the end of the war, the main building was severely damaged, the valuable collections distributed across Allied zones of occupation, the library staff had been killed or scattered, and 700,000 volumes either destroyed or lost.[9] With the formal dissolution of the State of Prussia in 1947, support for the library ended and the Prussian State Library ceased to exist.

After 1945, parts of the collection that had been hidden in what became the Soviet occupation zone were returned to the war-damaged Unter den Linden building in East Berlin. It first opened in 1946 as the Public Scientific Library (German: Öffentliche Wissenschaftliche Bibliothek). When further restoration work was completed in 1955, the library was renamed the German State Library (German: Deutsche Staatsbibliothek). The great domed reading room, however, remained a ruin in the center of the building.

A larger proportion of the collection wound up in the American occupation zone, including a cache of 1.5 million volumes hidden in a potash mine near Hattorf, and was moved to the University of Marburg in 1946. This collection first opened to the public as the Hessian Library (German: Hessische Bibliothek) and in 1949, as the last lost stores arrived, it was renamed the West German Library (German: Westdeutsche Bibliothek). Those parts of the collection that had been in the French occupation zone, mainly at Beuron Archabbey, were gathered to the University of Tübingen. In 1962 the Federal Republic passed a law giving administrative responsibility for all these collections to Prussian Cultural Heritage Foundation and endowed it with State funding. During the 1960s, the various stocks, services and personnel began to be relocated to West Berlin. To house it all, a grand new building complex on the Kulturforum was constructed near the Berlin Wall, just 1.5 km (0.93 mi) away from the library in East Berlin.[10]

After German Reunification, the two institutions were formally reunited in 1992. The new West Berlin building and the original East Berlin building became "one library with two homes" and the old State Library was reborn as the Berlin State Library.[11] From 2000 until 2012 Berlin State Library was refurbished by German architect HG Merz. The destroyed reading room, the core of the building, was replaced by a glass cube.

Many important items from the original collection are now located in Poland and territories of the former Soviet Union – declared as war reparations, sometimes controversially – such as the Berlinka Art Collection. The original score of Beethoven's 8th Symphony is a starker example of division: while the first, second and fourth movements are in Berlin, the third is kept in Kraków.[12] Conversely, it is estimated that about 10,000 volumes and 9,000 other items in the Berlin State Library are there as a result of Nazi plunder. Repatriation and self-criticism about these materials suffered from neglect, so in 2005 the Prussian Cultural Heritage Foundation established the Center for Provenance Research to speed up the process. Sometimes, however, the past cannot be mended. In 2008 a Library user found an encyclopedia entitled Religion in History and the Present Day with a bookplate indicating it once belonged to a Jewish theologian. Library staff managed to find his widow in Israel, but she wrote back: "I appreciate your offer to return this book to me, but I have no use for it now."[13]

The original main building was built between 1908 and 1913 by the Prussian Construction and Financial Directorate of Berlin, then responsible for public constructions in the city. The Neo Baroque design is by popular Wilhelmine court architect Ernst von Ihne and was further adapted by Alexander Baerwald, who was in charge of the construction management. In front of the building is an equestrian statue of Frederick the Great. The building was 40% damaged during World War II, and after the division of Berlin wound up in East Berlin. After delays and cost overruns, a 15 year restoration project was finally completed in January 2021, including a new translucent central reading room on the ruins of the old dome.[15] The central location is now the historical research library housing the collection up to and including 1945.[16]

This is the newer building in the Kulturforum on Potsdamer Straße in West Berlin, designed by Hans Scharoun with substantial participation by Edgar Wisniewski. Construction began in 1967 to house those parts of the library's evacuated holdings from the western Allied occupation zones at the end of World War II. After 11 years of construction, it was finally dedicated by Federal President Walter Scheel and opened to the public in 1978. It was renovated from 1999 to 2001. The building is currently being further redeveloped into a modern research library as a companion to the Haus Unter den Linden and will house the collection from 1946 onwards.[17]

• Westhafen: located in Berlin-Moabit, this building is a renovated granary and houses the newspaper collection and the children and youth library. It also serves as a temporary site for other major collections while the Unter den Linden building is renovated.
• Friedrichshagen Storage Magazine: located in Friedrichshagen and originally constructed in 1950 for various scientific agencies of the German Democratic Republic, this site was renovated and expanded in 2011 into a technologically advanced storage facility for cultural artifacts. It encompasses 22,000 square metres (240,000 sq ft) of climate-controlled space, and plans are in place to triple this size.
