  1. ReCAP DataCirculation FY13 Zack Lane ReCAP Coordinator July 2013 ReCAP Columbia University

  2. Findings • 109.6% increase in total charges to offsite collections from FY04 to FY13 • Meanwhile 35.7% decline for on campus collections • Offsite charges have leveled off over the past five years • Faculty (OFF) account for 40.4% of charges and 58.0% of renewals in FY13 • Offsite collections have more renewals than charges; it is the opposite for on campus ReCAP Columbia University

  3. Circulation Data • Circulation activity is only one measure of collection usage • System-wide circulation statistics are available for both offsite and on campus • Circulation data are accessible to all staff • Offsite collections can be identified by CLIO location format off,xxx. • ReCAP opened in January 2002 • Voyager circulation activity data is available from July 2003, the date of implementation • Data does not include Teacher’s College or Law Library ReCAP Columbia University

  4. Previous Studies • Previous study has been done: System-wide Circulation Data: Initial Analysis (.ppt) • Completed by ReCAP intern Steve Zweibel in Summer 2010 • Summarizes and visualizes system-wide data by activity type and patron group • Presents activity of both on campus and offsite collections; it is not ReCAP-specific • Includes observations, analysis and conclusions  ReCAP Columbia University

  5. Charts ReCAP Columbia University

  6. Charges to Offsite Collections • 109.6 % increase from FY04 to FY13 • Increase in circulation activity totals every year between FY04 and FY09 • One, small decline between FY09 and FY10 • Since FY09 the total charge volume has plateaued ReCAP Columbia University

  8. Offsite vs. On Campus Charges • Comparing offsite and on campus charges by volume • Offsite charge volume increased 109.6 %between FY04 and FY13 • On campus charge volume declined by 35.7%between FY04 and FY13 • On campus charges have declined every year since FY04 • N.B. On campus collection size declines each year; offsite collections grow each year ReCAP Columbia University

  10. Offsite as Percent of Total Charges • Growth of offsite collection usage can be evaluated using a ratio • Offsite/Total Circulation as percentage • Ratio has increased since FY04 • Since FY09 the ratio has been 6-7% • Data suggests that the leveling off correlates to increased renewals ReCAP Columbia University

  12. Charge Volume by Month • Monthly charges of both offsite and on campus 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 • Amplitude is higher for on campus collections – see charts by calendar month • 1:3 for on campus • 1:2 for offsite ReCAP Columbia University

  17. Offsite Charges vs. Renewals • Chart compares total volume of charges to renewals for offsite collections • Faculty and Grad request more offsite collections than Undergrads • Faculty and Grads 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 ReCAP retrieval rate as a result ReCAP Columbia University

  19. On Campus Charges vs. Renewals • Chart compares total volume of charges to renewals for on campus collections • Renewal behavior has changed significantly over time • Faculty and Grads Faculty have higher renewal/charge ratios • Undergrad loan periods were extended from four weeks to one term in January 2008 • Loan period had a stark effect on usage pattern, reducing the need for renewal ReCAP Columbia University

  21. Charge to Renewal Ratio • Calculates how many renewals per charge • Renewal behavior has changed over time • Offsite collections have been tending upward, indicating more renewals per charge • On campus collections trend downward, less renewals per charge ReCAP Columbia University

  23. Offsite Charges and Renewals by Patron Group • Faculty (OFF) accounts for the majority of offsite activity in FY13: • 40.4%of charges • 58.0% of renewals • Together Faculty and Grads (GRD) account for 76.7%of charges and 86.9%of renewals • Faculty charges have increased due to more Grads serving as adjunct faculty • This allowed Grads to have OFF set as primary patron group effective in Summer 2007 ReCAP Columbia University
