20.  Comparison of on campus and offsite collection charges by volume  On campus charge volume declined by 27.4% between FY04 and FY12  On campus charges have declined every year since FY04  Offsite charge volume increased 121.3% between FY04 and FY12  N.B. On campus collection size declines each year; offsite collections grow each year ReCAP Columbia University

25.  On campus and offsite charges can be compared using a ratio  The ratio of offsite to on campus increased from FY04 to FY012  Offsite collections are accounting for proportionally more activity ReCAP Columbia University

27.  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
