Book an Appointment with Friends of the San Francisco Public Library: Each donation appointment is limited to 20 boxes or 30 bags of items. If you have more items to donate, you can make additional appointments. For exceptionally large donations—estates, store inventories, libraries—we ask that you email firstname.lastname@example.org with the details so that we can make special arrangements. You can make an appointment up to one month in advance. Appointments are limited, and often fill up. Check back if no appointments are available.
