East Asian Circulation Data Looks at East Asian Library circulation activity Is only one measure of collection usage Presents data both EA specific and system- wide Circulation Desk uses several happening locations: East Asian, East Asian Reserves, Butler, and HSL EA Library data is available from the implementation of Voyager, July 2003 No usable data for non-circulating collections ReCAP Columbia University
East Asian Library Happening Location Data from East Asian Library Happening Location only (includes Reserves) Five primary types of circulation activity: charge, discharge, renewal, recall and hold Renewals and recalls are done in the OPAC Happening Location, dynamically by patrons themselves Circulation data for special collections pertains only to exceptions: Interlibrary loan Exhibits Scanning ReCAP Columbia University

Observations Total volume of charges has declined almost each year except FY08 23.3% decline from FY04 to FY12 Compare to 27.4% decline system-wide) Volume of discharge predictably mirrors charges until FY08 when renewals began to increase May be due to increased enrollment or new faculty Gap between charges and discharges is unusual ReCAP Columbia University

Charges vs. Renewals 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
