Materials placed on Reserve by instructors for use by students in conjunction with specific classes are housed in the Library's "Reserves" collection which is located behind the Circulation Desk.  Reserve materials range from photocopies of class notes to journal articles, and on rare occasions to course textbooks.  Circulation periods for these materials are determined by the instructor and range from two hours to one week.  Currently, only a very small number of Reserve items are available electronically so you must come to the Library in order to use Reserve items.
