Prior to USC's acquisition of the Los Angeles Master Chorale records, portions of the collection's photographic, audio only, and audiovisual works were digitized by Paroo -- an information management consultancy. The digital versions of the works have been copied to the USC Digital Repository. Access to both the analog and digitized versions of the audio only and audiovisual works is restricted. Users wishing to request access to the audio only and audiovisual works should email music@usc.edu.
