Part of the film collection has been put online in a catalogue by the ‘Stichting Vrienden van het Filmarchief’ (Foundation for Friends of the film archive at the University of Nijmegen) as an inventory at the time that they held the collection. In addition, the Film Archive made an inventory of its current collection in 2011.
