The operation of the University of Idaho Library is divided into Technical Services (UG 53) and Public Services. Prior to reorganization in 1993 the Public Services division of the University of Idaho Library was composed of three divisional libraries (Humanities, Social Science, and Science), Circulation and Interlibrary Loan. When the new library addition was occupied in 1993 the divisional libraries combined to form a centralized reference area.
