 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 ReCAP Columbia University
