ReCAPColumbia University

Looks at circulation activity of each library separately

Is only one measure of collection usage Presents data both department specific and

system-wide Each Circulation Desk uses several

happening locations, including [Butler, BorrowDirect, and HSL]

Circ data is available from the implementation of Voyager, July 2003

Geology Circ Data



Happening Location Data from Happening Locations include

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 by Patron Group at Geology Line charts represent usage by year and

month Patron Group assignations have changed:

◦ Teaching assistants : in 2008 grad students were given primary group OFF instead of GRD

Pie charts break down data for FY12 only Bar chart compares patron group charges

for each fiscal year

Observations Undergraduates heaviest users in recent

years Large upswing in activity during FY10-FY11

can be attributed to undergraduates Explanation? Relatively steady activity from month to

month, even during slow summer and winter periods


Monthly Patron Group Activity Monthly view reveals periodicity in sync

with the academic calendar for graduates, undergraduate and visitors

Faculty use is more evenly distributed through the months

Faculty have a larger proportion of activity during the summer months
