There are two types of reserves: hard copy and electronic (ERes).

• The Reserve desk houses personal hard copies of items as well as materials which are in high demand and/or short supply, and which have been designated by the instructor to be available for check out for limited periods of time (typically 2-72 hours).
• Electronic reserves are password protected and accessible online via
  ERes. You'll need your course information, including a password given to you by your instructor.
