  1. Circulation Data: Geology Library FY13 Zack Lane ReCAP Coordinator July 2013 ReCAP Columbia University

  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] • Circdata is available from the implementation of Voyager, July 2003 ReCAP Columbia University

  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 ReCAP Columbia University

  6. Observations • Data for Geoscience begins FY08 • Large increase in circ charges at Geology during FY10-FY11 • Explained by Science Reserves temporarily shelved during transition to new building • Decline in circ activity at Geology of 50.2% • Increase in circ activity at Geoscience of 59.6% ReCAP Columbia University

  7. Circ Activity by Collection • Reserves increasingly account for larger proportion of circulation activity ReCAP Columbia University

  10. Circ Activity by Sub-Collection • General collections used by faculty in greater proportion than other departments ReCAP Columbia University

  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 ReCAP Columbia University

  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 ReCAP Columbia University

  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 ReCAP Columbia University
