FIAF, the International Federation of Film Archives, has been dedicated to the preservation of, and access to, the world’s film heritage since 1938. It brings together the world's leading non-profit institutions in this field. Its affiliates are committed to the rescue, collection, preservation, screening, and promotion of films, which are valued both as works of art and culture and as historical documents. When FIAF was founded in June 1938, it had four members. As of May 2018, it comprises 166 institutions in 75 countries – a reflection of the extent to which film heritage has become a world-wide concern. After nearly 80 years of experience in this field, FIAF has grown to be the most important global network of cinematheques and film archives.
