The collections of the Centre for Theatre and Film Studies comprise around 36,000 books and magazines; 120,000 photographs; 8,000 films and videos; 88,000 theatre articles; 600 pieces of stage and costume design; etc.
The materials have been collected since 1946 when the Academy of Acting (predecessor of the Academy of Theatre, Radio, Film and Television (AGRFT)) was established. The oldest is the collection that includes materials about the artistic, research and pedagogical work of the AGRFT, from essays to doctoral dissertations, manuscripts, sketches of sets and costumes, photographs as well as recordings of the students' theatrical, film and TV productions, etc. One of the oldest is also the collection that preserves documents on Slovene partisan theatres during the Second World War. Manuscripts and other legacy materials by theatre and film directors (Fran Žižek, Slavko Jan, Mile Korun), actors (Emil Kralj, Marija Vera), dancers (Pino and Pia Mlakar), scenographers (Bojan Stupica), historians, and former professors (Josip Vidmar) are also included in a separate collection.
Furthermore it is possible to search the collection with documents from two international institutions: the International Federation for Theatre Research (IFTR), which promotes collaboration and the exchange of information between individuals and organisations concerned with theatre research; and the SIBMAS International Directory of Performing Arts Collections and Institutions, which provides basic information about over 700 institutions with material relating to the performing arts and about the collections which are to be found within those institutions.
Yet another is the collection of Slovene, European, and world theatre and cinema. It includes a library of recorded sounds, a library of film and video materials, as well as theatre and film reviews, newspaper clippings, posters and photographs.
A specialised library, comprises a large theatre archive and a film archive.
Research projects conducted by the Centre during the last decade were: Historical Transformation in the Shaping of National Theatres (1994–1996); Framing in Cinematography (1994–1996); Theoretical and Informational Basis of Slovenian Theatre History (1998–1999); Fundamental Research on Theatre, Radio, Film and Television in Slovenia (2000–2003); and Dynamic of Changes in 20th-Century Slovenian Theatre (2007–2009). The results have been published in books.
The Centre collaborates with other departments within the Academy as well as domestic and foreign institutions. Most of the projects are funded by the Slovene Research Agency (ARRS).
