Manuscript Collections

The Archives houses close to 200 manuscript collections, of which the majority are the papers of Caltech's faculty and administrative officers. Among these are the papers of Lee A. DuBridge, Richard Feynman, George Ellery Hale, Theodore von Kármán, Robert A. Millikan, and many others.

Photographs

The Archives maintains PhotoNet, an online database of thousands of images from the Archives' collections.

Oral Histories

Since 1978 the Archives has conducted an oral history program centered on the Caltech community and its distinguished scientists. More than 150 interviews have been completed and most are open to researchers. Also included are interviews on specific projects, such as the Keck Telescope and LIGO. The oral history project is ongoing.

Books

The Archives' rare and landmark book collections are cataloged in the Caltech Libraries catalog, CLAS.
