Most of the films screened by film societies in Australia are selected from the more than 6,000 titles held in the Non-Theatrical Lending Collection, owned and managed by the National Film and Sound Archive. This is a world-renowned collection of 16 mm feature films and short films and more recently DVDs which are available to film societies for a service charge. There is another lending facility within the Archive of mainly Australian films which on different terms are also available for screening. Protecting these invaluable resources has been one of ACOFS' main activities over the past few years.
