|Audio Visual Collection
The Caltech Archives' holdings include an extensive library of audio and video recordings of lectures and other scientific presentations, including major series such as the Watson Lectures, and of major campus events such as commencements and presidential inaugurations. The crown jewel of our audio holdings are the original tapes of the 1961–1962 Feynman lectures on physics, which have been published in both cassette and CD format by Perseus Books Group.
Also of special interest is the series of about 60 interviews with physicists worldwide conducted by Caltech's Kip Thorne in the course of research for his book, Black Holes and Time Warps: Einstein's Outrageous Legacy (1994).
Most audio and video holdings are preserved in their original format. We are incrementally migrating older analog media to digital formats for preservation and to make them accessible online.
Audio and video material may be identified through a search of our catalog, usually by a name or keyword.
