  2. Social Work Circulation Data • 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. ?SW Library Background • ?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

  4. SW Library Happening Location • 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

  7. Observations • 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 • Staff may be responsible for most holds ReCAP Columbia University

  8. Circ Activity by Collection • Over the first few years charge activity is split evenly between stacks and reserves collections • Since FY09, activity has tilted towards Reserves • Charges to SW Stacks has declined steadily each fiscal year • Offsite charges should be placed in the Butler Happening Location • Data unavailable for non-circulating collections ReCAP Columbia University
