Circulation Data: Avery Library FY13 Zack Lane ReCAP Coordinator July 2013 ReCAP Columbia University
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 there…?) • Circ Desk uses several happening locations: Avery, Butler, BorrowDirect, HSL • Separate presentation available for system-wide data and analysis ReCAP Columbia University
Avery Circ Happening Location • Five primary types of circulation activity: charge, discharge, renewal, recall and hold • Most renewals and recalls are performed dynamically by patrons in the OPAC happening location • Note: circulation data for Avery includes both on-campus and Offsite collections • Five primary patron groups: • ACO • GRD • REG • OFF • VIS ReCAP Columbia University

Observations • Charge volume at Avery in FY13 is 53.1% of FY04 • System-wide it is 67.7% of FY04 • Volume of discharge predictably mirrors charges • Other types of circulation activity happen in much lower volume • Renewals, recalls and holds occur primarily via CLIO ReCAP Columbia University
Circ Activity by Collection • Over time Reserves and Ware have taken a smaller share of activity • Likely linked to transfer of Ware collections to ReCAP • Offsite activity has doubled as transfers continue • Charges for non-circulating collections are made to carrels and offices but do not accurately reflect aggregate usage ReCAP Columbia University

Circ Activity by Sub-Collection • Architecture, Fine Arts and Offsite collections are commonly charged to patron group ACO (carrels and offices) • Circulating Ware collections are charged to all user groups • Note: Offsite Ware collections can be delivered to any department library • Reserve collections have shown steep decline likely due to transition to e-reserves ReCAP Columbia University

Avery Circulation by Patron Group • Patron Group definitions have changed: • Adjunct faculty, in 2008 grad students were given primary group OFF instead of GRD • Steady level of charges to patron group ACO • Declines for Reserves and Ware • Suggests primary, on-shelf collections maintain usage for past decade • Declining usage of hardcopy Reserves has put most dramatic effect on overall circulation statistics ReCAP Columbia University

Patron Group Activity • Charges to ACO (carrels) account for greater portion of activity • Graduate students are the single largest user group • “Faculty” usage likely due to grad students with temporary OFF borrowing privileges ReCAP Columbia University
