Book an Appointment with Friends of the San Francisco Public Library: Thank you for your interest in donating to us. Due to high demand, you might find that no appointments are available right now. If that's the case, please check back on Friday, when we typically release additional dates. Large Donation appointments (up to 20 boxes) are currently full early June. Please pack your books flat in boxes or bags. This protects them against wear and damage and makes it easier for us to stack boxes and bags in our limited space.
