Founded in 1949, the Deutsches Filminstitut – DIF is the oldest cinematic institution in Germany and also one of the country's largest.
Along with the Bundesarchiv/Filmarchiv (Federal Film Archive) and the Stiftung Deutsche Kinemathek (Foundation of the German Cinemathèque), both in Berlin, the DIF in Frankfurt is a full member of the Deutscher Kinematheksverbund (German Federation of Cinémathèques), sharing with the above mentioned organisations the duties of a central German Cinémathèque. The institute is a full member of the Fédération Internationale des Archives du Film (FIAF) and of the Association des Cinémathèques Européenes (ACE).
To collect, process and analyse information on film is one of the main purposes of the DIF. A second purpose is the collection of films, their preservation and, if necessary, restoration in order to bring them back to the screen.
