Our Organization: Access & Lending Policies

Access & Lending Policies

Access to the libraries of Caltech varies based on day of the week and patrons status. For the most up-to-date library hours, please visit the View All Hours page. The Caltech Library provides a safe space for its community to study or work on academic endeavors. Behavior contrary to this principle will not be tolerated and Campus Security will be notified immediately.

The Library has four categories of users: Current Caltech ID Holders, Caltech Affiliates, Friends of the Caltech Library, and Government Documents & Archives Users (by appointment only). Only Current Caltech ID Holders and limited Caltech Affiliates have borrowing privileges and access to Library services - please see our What Can I Access? page.
