6. Observations Charge volume at Barnard in FY13 is 69.8% of FY04 volume
System-wide there has been a 27.4% decline
Volume of discharge lower than charge, suggesting that Barnard collections are frequently returned at other departments
Other types of circulation activity happen in much lower volume
Majority of renewals occur in the OPAC happening location

7. Circ Activity by Collection
Recently there is increased activity for Media, IMATS and Borrow Direct
Is this attributable to new collections, new services or reclassification?
The majority of circulation activity is for the general, circulating collection

Reserves most heavily used by undergraduates
Charges for Reserves have fallen by more than half in 10 years, likely due to e-reserves
