2. Geology Circ Data
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

3. 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

14. 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

18. 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

19. 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
