To celebrate their fiftieth anniversary, the Caltech Archives will host a three-day open house for the campus community, on Wednesday, April 18; Thursday, April 19; and Friday April 20, from 12:00pm to 2:00pm. Come and visit the Archives to marvel at their treasures from up close, and to take part in an exclusive behind-the-scenes tour of the facility.

The Caltech Archives collects, preserves, organizes, and makes available the history of science and technology at Caltech. Our collections include the papers of Caltech scientists and engineers, such as their letters and laboratory notebooks, as well as photographs, scientific instruments, art, rare books, email, websites, and video.
