Do you have any questions not answered in these Web pages? If you do, please feel free to contact us with them, by whichever of the following means you prefer:
mail on editorial or production matters: send to 2906 Forest Ave., Berkeley, CA 94705
mail about orders or on business matters: send to 11508 Green Rd., Wilton, CA 95693
telephone: from telephones within the United States, call (800) 305-7942. For calls from outside the United States, toll-free service is not available, but for editorial matters, a toll call may be made to (510) 540-6538.
Shipping questions: our books are shipped by a commercial firm specializing in this work. We can usually provide a UPS tracking number for commercial shipments, but individual orders are normally sent via U.S. Postal Service mail, which means packages cannot be tracked and delivery dates cannot be estimated. But if an order seems to be overdue, please call us and we will look into the situation.
