How performance is measured
Circulation statistics are generated from the Library’s automated circulation system. Reports are generated on a monthly basis.
SF Public Library projects monthly target ranges using pre-COVID historical data to account for seasonality and predictable rates of change in service provision. The number displayed on the scorecard page is the number of materials circulated in the latest month for which data are available.
