Ask to check out a Reserve item at the Circulation Desk.
Course reserves are textbooks or other books, videos, articles, etc. that have been reserved by an instructor for their students' use. Reserve items usually check out for only 2 hours at a time, but some reserve items check out overnight or for a week.
Every college or university library offers course reserve items, but no library has every textbook for every class. We only have the ones that instructors have specifically brought to us to put on reserve. More about course reserves.
