The German Library in Frankfurt am Main (Deutsche Bibliothek abbreviated: DB) was a predecessor of the German National Library (DNB). From 1947 to 1990 it was the West German counterpart to the Deutsche Bücherei in Leipzig, founded in 1912, with the task of collecting German documents and publishing the national bibliography. After the reunification of Germany in 1990, the German Library and the German Library were merged to form "The German Library". Since 2006 it has been called the "German National Library". In 2006, around 8.3 million of the total holdings of the German National Library of 22.2 million units were stored in Frankfurt am Main. At the end of 2011, out of a total of around 27 million media copies, 10 million were archived in Frankfurt.
