A professor can ask that an item be placed on reserve for students. It maybe a required textbook or a recommended reading for class. This means there is a copy held so that students can access it at almost any time for their studies. If it is at the circulation desk, you can check the item out for 2 hours.
Why are there books on this list that aren't for my class? Fair question! We complied this list of items on reserve by department. That way you can just look up the department and see if an item is on reserve. You don't have to do it for each course code, and we don't always know all the courses a book might be used for.
Only items that faculty members have requested be placed on reserve are here. If you don't see your textbook ask your professor to place a request or reach out to their subject librarian about placing a request.
