2.  Looks at Engineering Library circulation activity  Is only one measure of collection usage  Circulation Desk uses several happening locations: Engineering, Butler, BorrowDirect, HSL  No circulation data for non-circulating collections ReCAP Columbia University

3. ReCAP Columbia University  Focus is on data from Engineering Library Happening Location  Five primary types of circulation activity: charge, discharge, renewal, recall and hold  Most renewals, recalls and holds are placed dynamically by patrons in the OPAC happening location (via “My Library Account”)  NB: circulation data includes primarily on campus collections

6. ReCAP Columbia University  Total volume of charges has had decline of 37.7%  System-wide decline of 32.3%  Volume of discharges mirrors charges  Slightly larger volume of discharge suggests that Engineering may be desirable location for circulation returns

7. ReCAP Columbia University  More than half of the activity at the Engineering Circulation desk is for reserve material  Proportional activity for reserve collections has increased over the last decade from 40% to 60%
