  • Cal Poly faculty, staff and students must present their current university photo identification card to borrow library materials.
  • Other affiliated users must present their library-issued card, and may also be required to present a photo ID.
  • Borrowing privileges may not be transferred to another borrower, and you are responsible for all materials checked out on your record.
  • For your protection, if you lose your library card you must report it to the Library immediately.
