A survey of the ten university libraries considered to be most comparable to George Mason University (GMU) in interlibrary loan (ILL) activity was undertaken for comparison purposes. To develop a series of recommendations for GMU with respect to ILL, the following areas were considered and are addressed in this report: (1) Divisional Responsibility for ILL Service; (2) Patron Use; (3) Fill Rate, Standards of Service and Turnaround Time; (4) Workflow; (5) Automation, Equipment and Location; (6) Costs of ILL Service; (7) Fees to GMU Patrons; (8) Charges to Borrowing Libraries; (9) Resource Sharing in the Consortium Environment; (10) Resource Sharing in the State of Virginia; and (11) Staffing. Specific recommendations are provided at the end of each section, and additional recommendations for policies and procedures are summarized in a concluding statement. A bibliography and seven statistical comparative charts are included. (THC)
