Staatsbibliothek zu Berlin: the reunification of Germany’s largest library

German reunification has enabled the unification of the two libraries created out of the division of the Preussiche Staatsbibliothek. After reorganisation, and once the system of distribution between the two sites of the current Staatsbibliothek zu Berlin–Preussicher Kulturbesitz has been established, each will be equipped with a reading and research room, one focusing on historical collections, the other on “modern times” and measures will be taken to limit the disadvantages of this double location.
