With the unification of Germany on 3 October 1990, the Deutsche Bücherei Leipzig and the Deutsche Bibliothek Frankfurt am Main were merged in the new institution Die Deutsche Bibliothek. The "Law regarding the German National Library" came into force on 29 June 2006. The expansion of the collection brief to include online publications set the course for collecting, cataloguing and storing such publications as part of Germany's cultural heritage. The Library's highest management body, the Administrative Council, was expanded to include two MPs from the Bundestag. The law also changed the name of the library and its buildings in Leipzig, Frankfurt am Main and Berlin into "Deutsche Nationalbibliothek".
