of Cologne, the founding seat of the DFG, in the fall of 1949, finally led in 1952 to the conversion of the German Library into a foundation under public law. The city of Frankfurt and the state of Hesse acted as the founders, the Federal Republic of Germany, represented by the Federal Ministry of the Interior, which saw the protection of society from communist influences as an essential mandate, and the Börsenverein as contributors.: S. 331 In 1952, each institution contributed 60,000 DM (the federal government with 65,000 DM) annually to the financing of the library. In 1954, the contributions were 71 percent higher. The Börsenverein reduced its contributions from 1956.: S. As early as 1953, 337 space problems made it necessary to distribute the holdings to three locations in the city. In 1959, the German Library moved 480,000 units into a new building on Zeppelinallee. Kurt Köster became the new director. The inauguration of the new building was on April 24, 1959 in the presence of Federal President Theodor Heuss. In 1961 the library had 143 permanent positions. From 1963, the Börsenverein excluded all members who did not submit copies to the German Library from the association.

In 1969 the Bundestag passed the "Law on the German Library", which became a federal institution under public law and was subject to legal supervision by the Federal Ministry of the Interior.

In 1970 the German Music Archive in Berlin was attached to the German Library and in 1976 Günther Pflug became the new General Director. In 1971 the Deutsche Bibliothek had 270 posts, the maximum value before the merger with the Deutsche Bücherei was reached in 1981 with 331 posts. The construction of an online catalog began in the mid-1980s: The two libraries in Frankfurt and Leipzig published largely identical national bibliographies until 1990. In 1966, the German Library began to compile its bibliography with
