St Paul’s Books is operated by St Paul’s Episcopal Church in
Walnut Creek, California, which has been part of the community for over 120
years.Books are obtained from the
volunteer-run rummage sale which sells donated items in the spring and fall
each year.All proceeds from these
sales are donated directly and only to charities.We reuse materials as much as possible for packaging books for
shipment, and books are taken to the post office by bicycle.
