Circulation/Reserves: Check out books and other library materials using your university ID at the Circulation Desk.  You can also place search requests for volumes you can't find on the shelves and request recalls on books currently checked out or located at the Annex or Depository.  The right half of the Circulation Desk is the Reserve Desk.  Supplementary course readings, such as books and articles, are often placed on Reserve by instructors.  Use your university ID to check out Reserve material. ERes is the electronic reserve system at MU Libraries.  It is linked from the MU Libraries Home Page.
