Reserve material may be checked out overnight, unless it is for library use only. The majority of material on reserves has a 2-hour loan period (rounded to the nearest hour). Below is a list of checkout and return times for each library. Please note that the checkout times and return times change for finals hours. Reserve material becomes due one hour after opening the next business day. The Rivera and Orbach Science Libraries allow reservations for overnight checkouts. The reservation needs to be made in-person on the day requested for overnight loan. Check the library hours page to see the times we open.
