Materials placed on Reserve by instructors for use by their students in conjunction with specific classes are housed in the "Reserves" collection which is located behind the Circulation Desk.  These 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 instructors and range from two hours to one week.  Instructions for faculty can be found in the section on "Library Services for CSUS Faculty".
