The reserve desk is at the Circulation Desk on the fourth floor of the Rasmuson Library. This is where professors put books and articles on reserve for students to use. The usual period of time you may check out reserve items is 2 hours, and most items cannot be taken out of the library. The professor must arrange to put items on reserve with the Circulation Department. The library does not usually have the class's textbook unless the professor has arranged to put it on reserve ahead of time.
