CSNSF maintains a library and bookstore at our main office in Houston. There is also the online Bowen Theory Resource Store that offers books and materials for sale. You can pay by check or credit card if you download and print the order form and send it to CSNSF with your payment and shipping. Some recommended books and materials are linked to information about where you can order them directly. A percentage of the purchase price for each Amazon item will be donated to CSNSF by Amazon.com. Unless indicated otherwise, shipping for a book or DVD is $5.00.
