The north side of the fourth floor has reopened for use.  The books on that floor are now stored on new mobile high-density shelving.  Library users who do not have experience with this type of shelving should ask a staff member at the circulation desk on the 2nd floor for assistance with retrieving a book. The south side of the floor, including the study rooms, remains closed until the  completion of the stack renovation project.  Public Safety has placed caution tape around the perimeter advising users not to enter that area.
