The Caltech Library is committed to serving the teaching, research, and academic needs of its students, faculty, and staff. Access to collections, borrowing privileges, and use of computers are limited to those affiliated with Caltech.
The Caltech Library have heavily used, highly specialized collections which can be largely unsuitable for access to general information. In addition, due to our licensing agreements, off-campus access to electronic resources to non-Caltech individuals is restricted. For these services, we highly recommend visiting other local libraries.
The Caltech Library is primarily for the Caltech community (including Caltech Affilates) but external researchers may have limited access to Sherman Fairchild Library between 8am-5pm Monday through Friday. A Caltech ID card is required for access after 5pm during the week and all day on Saturdays and Sundays. The other library locations on campus are primarily for Caltech students, faculty, and staff. Visiting scholars are encouraged to contact the Library about access to another library on campus.
For more information, please visit our Rules of Access.
Borrowing of Caltech materials are limited to members of the Caltech community and affiliates of the Institute. Please visit our Borrowing page for more information.

Simply take your Alumni Association card to the Sherman Fairchild Library circulation desk from 8am to 4:30pm Monday through Friday and sign up for library access.
