The Stanford Speech Collection consists of audio recordings on open reel tape of speeches, lectures, and panel discussions at or sponsored by Stanford University from the 1950s through the 70s. Many recordings were produced and edited for broadcast on campus radio station KZSU (especially those tapes from 1969-1971).
The Archive of Recorded Sound's Non-Commercial Disc Collections consist of over 10,000 phonographic disc recordings from a variety of donors, the majority of which are either broadcast transcriptions or instantaneous recordings. None were ever available for sale to the general public, and many are unique.
