  1. Circulation Data: Avery Library Zack Lane ReCAP Coordinator July 2012 ReCAP Columbia University

  2. Avery Circulation Data • Looks at Avery Library circulation activity • Is only one measure of collection usage • Majority of Avery collections are non-circulating • No circulation data for non-circulatingcollections (or is it??) • Presents data both Avery specific and system-wide • ?Circ Desk uses several happening locations: Avery, Butler, BorrowDirect, HSL ReCAP Columbia University

  3. Avery Circ Happening Location • Five primary types of circulation activity: charge, discharge, renewal, recall and hold • Most renewals and recalls are done in the OPAC happening location, dynamically by patrons themselves • Note: circulation data includes primarily “on campus” collections • Five primary patron groups: • ACO • GRD • REG • OFF • VIS ReCAP Columbia University

  8. Observations • Charge volume at Avery has declined by 41.7% since FY04 • System-wide there has been a 27.4% decline • Volume of discharge predictably mirrors charges • Other types of circulation activity happen in much lower volume • Majority of renewals occur in the OPAC happening location ReCAP Columbia University

  9. Avery Circulation by Patron Group • Closer look at patron group breakdown • More than half total charges were to ACO in FY12 • Patron Group definitions have changed: • Adjunct faculty, in 2008 grad students were given primary group OFF instead of GRD • Monthly patterns fit seasonal curves of academic calendar ReCAP Columbia University

  23. System-wide Circulation Data • System-wide circulation statistics are available for both on campus and offsite collections • Circulation data are accessible to all staff • Offsite collections can be identified by CLIO location format off,xxx. • System-wide data is available from July 2003, the date of Ex Libris Voyager implementation ReCAP Columbia University

  24. On Campus vs. Offsite Charges • 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

  26. Monthly Onsite vs. Offsite Charges • Monthly charges of both onsite and off-site collections are in phase with the academic calendar • Peaks in the middle of Fall and Spring terms • The pattern of offsite charges is more apparent when viewed alone ReCAP Columbia University

  29. On Campus vs. Offsite Charges • 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

  31. Charges vs. Renewals • 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
