Local Libraries The Millikan Library and the Sherman Fairchild Library of Engineering and Applied Science are open to the Caltech community from 8 a.m. to 1 a.m. weekdays and 9 a.m. to 1 a.m. weekends and Caltech holidays.
Closing is at midnight during the summer.
Because these libraries have small, heavily used, and highly specialized collections, and provide very limited seating, they are largely unsuitable for access to general information. For these services we highly recommend visiting other local libraries . After 5 p.m. weekdays and on all weekends and holidays, access will be granted only to those individuals carrying valid Caltech identification. All categories of borrowers, once registered, are entitled to entrance during all hours of operation. Graduate level status and the recommendation of two members of the Caltech Faculty or administration is required.
