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
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
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

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
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

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
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

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

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
