monasterial collections, however, were given to the Royal Library (Königliche Handbibliothek), founded by King Frederick I in 1810. This old-type court library (since 1886: Königliche Hofbibliothek) was only incorporated to the collections of the public library much later. In 1820, the library moved to the Invalidenhaus, a former military housing complex in Stuttgart. At nearly the same location, a new building was erected from 1878 to 1886. At this time, the library was renamed Königliche Landesbibliothek (Royal State Library). After the end of the monarchy, the institution was again renamed and gained its current name Württembergische Landesbibliothek. The library was nearly completely destroyed in World War II. The most valuable items had already been stored at a safe place outside Stuttgart, but approximately half of the collection (over 400,000 volumes) was lost in the fire that followed an air raid on 12–13 December 1944. The losses included all literature after 1930, many complete thematic sections, many newspapers and magazines and most of the former Court Library. Of the buildings, only an administrative building (containing the catalogs) survived. After the war, the library tried to fill the gaps in its collection. Regional publishing houses tried to help achieve this goal by donating large numbers of books to WLB. Horst Linde designed a new library building that opened at the former location on 3 August 1970. Special collections Manuscripts Collection, holding over 15,000 manuscripts.
