Audio-Visual Recordings
Audio-visual recordings are often valued for the authenticity and sense of closeness they bring to the the speeches, sporting events, interviews, newscasts, and performances they document. These primary sources can also be compiled to create a useful secondary source, for example, Ken Burns's Baseball documentary is a secondary source created from a variety of primary sources.
Because handling and play back of audio-visual recordings can easily damage the contents, archives often make reference copies for researchers to use.
