Access to audiovisual materials in this collection is available through digitized access copies. Researchers may view an item's original container, but the media themselves are not available for playback because of preservation concerns. Materials that have already been digitized are noted in the collection's finding aid and can be requested in our reading room. Materials not yet digitized will need to have access copies made before they can be used. To request an access copy, or if you are unsure if an item has been digitized, please contact [repository contact information] with the collection name, collection number, and a description of the item(s) requested. A staff member will respond to you with further information.
