  2. Health Sciences Circulation Data • Looks at HSL circulation activity • Is only one measure of collection usage • Presents data both HSL specific and system-wide • Circulation Desk uses several happening locations: Health Sciences Circ, Health Sciences Reserves, Butler, and BorrowDirect • HSL Library data is available from the implementation of Voyager, July 2003 • No usable data for non-circulating collections ReCAP Columbia University

  3. HSL Happening Location • Data from HSL 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

  21. On Campus vs. Offsite Charges • 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
