2.  Looks at Social Work Library circulation activity  Is only one measure of collection usage  Presents data both SW specific and system- wide  ?Circ Desk uses several happening locations: Social Work, Butler, BorrowDirect, HSL  No circulation data for non-circulating collections ReCAP Columbia University

3. ReCAP Columbia University  ?Social Work Library became independent entity in August 2004  ?Opening of new Social Work building  ?Print collection was previously part of Lehman Library in SIPA  ?Transition period between August 2004 and May 2005  ?Two happening locations: ◦ Social Work Circ. Deck ◦ SW Circulation Desk

4. ReCAP Columbia University  Data collated by happening location  Social Work Library became independent entity in August 2004  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

7. ReCAP Columbia University  Total volume of charges has fluctuated  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

8. ReCAP Columbia University  Almost 3/4 of all charges are to graduate students  Patron Group definitions have changed: ◦ Adjunct faculty, in 2008 grad students were given primary group OFF instead of GRD  Pie charts break down data for FY12 only  Bar chart compares patron group charges for each fiscal year

21.  System-wide circulation statistics are available for both on campus and offsite collections  Circulation data are accessible to all staff Circulation data are accessible  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

22.  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

24.  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

27.  On campu 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

28. ReCAP Columbia University

29.  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
