Our Open Day in Frankfurt am Main on 12 November 2023 officially ended the year of celebrations marking the 111th anniversary of our foundation. Some 1,600 visitors seized the opportunity to take a look behind the scenes of the German National Library in Frankfurt am Main: from the roof down to the extensive underground stacks, on guided tours, tours of exploration for children and young people and visitsto the German Exile Archive’s 1933–1945 exhibitions.
