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

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

6. Observations Total volume of charges down overall since FY04
40.5% decline from FY04 to FY13
Compare to 32.3% decline system-wide
Charge volume fluctuated FY04-FY08
Since FY09 the total volume consistently rose by a small margin until FY13
Larger volume of discharge in FY08 may be attributable to project processing collections for transfer to ReCAP

14. HSL Circulation by Patron Group
All status patron/pseudopatron charges are excluded
Special patron group HSA is included
Both REG and GRD show significant declines over the past decade – primarily undergraduates and graduates
OFF (faculty) usage has been steady
Drop in undergraduate borrowing between FY07 and FY08 is attributable to intercampus delivery

25. Observations Patron Group definitions have changed:
Adjunct faculty : in 2008 grad students were given primary group OFF instead of GRD
Almost 85% of all charges are to graduate students and faculty in FY13
Graduate and undergraduate charges have been declining
Peak borrowing period is Fall semester
Faculty activity is consistent throughout the calendar year

26. HSL Circulation by Patron Group
Different patterns of usage by patron group
Grads and Undergrads use Reserves often
Faculty drawing much material from Morningside Campus
Heavy borrowing by graduate students in fall compared to spring may indicate adjustment to med school – “learning how to study”
