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-circulating collections (or is it??) Presents data both Avery specific and system-wide ?Circ Desk uses several happening locations: Avery, Butler, BorrowDirect, HSL ReCAP Columbia University
ReCAP Columbia University 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 Five primary patron groups: ◦ ACO ◦ GRD ◦ REG ◦ OFF ◦ VIS

ReCAP Columbia University Charge volume at Avery has declined by 41.7% since FY04 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 Closer look at patron group breakdown More than half total charges were to ACO in FY12 Patron Group definitions have changed: ◦ Adjunct faculty, in 2008 grad students were given primary group OFF instead of GRD Monthly patterns fit seasonal curves of academic calendar

On campus 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
