If you know what course reserve item you need, simply go to the Information Desk on the first floor of the library with your ONU ID, which serves as your library card, and tell the person there what item you need. It is helpful if you know the call number and the title of the item, but all you really need to know is the title.
If you don't know what course reserve item you need, you can search for course reserves using the link below. Search by the number or name of your course or your instructor's name.
