Terms of Sale

All sales are subject to availability. We make every effort to ship orders within two business days; often they are shipped the same or next business day. Our preferred payment methods are major credit cards and PayPal. We will accept payment by US bank check and money order for domestic purchases only; we regret we cannot accept payment via money order or check for international orders. Library and institutional billing requirements are accommodated. Virginia residents and sales are subject to state sales tax of 6%


Shipping costs are based on books weighing 2.2 lbs., or 1 kg. Multi-volume sets, heavy and oversized books may require additional shipping, particularly if shipped internationally. In this event, you will be contacted before the order is processed. The above noted exceptions may apply.


We accept returns for any reason within seven days of receipt, provided we are notified in advance and the book is returned in the condition it was sold. If the book are not represented accurately we will cover return media rate shipping.
