CHARGES: Offsite % of Total
Chart compares total volume of charges to renewals for Offsite collections
Graduate students and Faculty request more Offsite collections than Undergraduates
Graduate students and especially Faculty have higher renewal/charge ratios
Over time, these two patron groups tend to renew more than charge
CUL may expect to see steady or decreasing request volume as a result
