Leaving every 30 minutes starting at 1:00 PM, guests of the First-Year Families Plus weekend will be shown around Harvey S. Firestone Memorial Library, considered one of the largest open-stack libraries in existence. Firestone serves as the main library on campus, home to Special Collections, and assumes primary responsibility for the humanities and social sciences. Since its founding, the library at Princeton has grown from a collection of 474 volumes in one room of Nassau Hall to more than 11 million holdings in approximately 12 buildings throughout the campus. To explore the other branches, please visit the library website for branch opening hours (https://libcal.princeton.edu/hours).
