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

Health Sciences Circulation Data



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

Comparison of Circulation Activity at Health Sciences Library

Charges Discharges Renewals Recalls Holds


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

FY13 Charge Activity at Health Sciences by Patron Group


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


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”
