The audiovisual materials supplement the printed materials related to Nirenska's choreography. Many VHS videotapes and a few 8 millimeter films document dances choreographed during Nirenska's residence in the United States. There are also numerous audio recordings of rehearsals. The video and audio recordings are significant not only for documenting choreographic works, but also for preserving the music of some contemporary women composers. Record albums of music used for accompanying Nirenska's dances are also contained in the collection.
