Katalog der Deutschen NationalbibliothekThis website contains the catalog of the Deutsche Nationalbibliothek, formed by the merging of the Deutsche Bücherei in Leipzig (founded 1912, later the national library of East Germany) and the Deutsche Bibliothek in Frankfurt am Main (founded 1947, later the national library of West Germany). It contains citations to monographs, periodicals, maps and atlases, dissertations and translations out of German into other languages, and foreign language works on Germany and German literature collected by the national libraries of Germany since 1913. Searching the Deutsches Exilarchiv, 1933-1945, is also provided.
