You can use OskiCat to search for books and other items on course reserve. Click on the Course Reserves tab at the top of the screen, and then enter the department and course number OR your instructor's name. To retrieve the item you're looking for, write down its library location and call number. At most UCB libraries, reserves are kept behind the circulation desk - give the call number to a desk staffer, who will retrieve it for you. Your Cal 1 Card is your library card, which you will need to check the item out.
