Most audiovisuals are in core biomedical subjects and are in English.
Audiovisual Reference Assistance Reference Section staff are available to provide assistance. Help in identifying and locating audiovisual titles in NLM's collection as well as consultative and referral services are offered. Audiovisual Loans Most of the audiovisuals in NLM's collection are available for loan to any library in the United States. Requestors who cannot obtain medical audiovisuals locally and cannot come to view the materials may secure material through the interlibrary loan service by requesting items through their local libraries. Libraries should first send requests to local sources, and send requests directly to NLM only for those titles not held in their regions.
