Precision: A Measure of Progress

Books are offered subject to prior sale. You may return any book within 14 days for a refund; if it was not as described, we will also refund return shipping costs (but please e-mail us first). You can place credit card orders through Biblio, or we will ship upon receipt of payment by check or money order. Sales tax is collected by Biblio and remitted directly to your state, where applicable. SHIPPING IN UNITED STATES: Books are priced postpaid, so there are no additional shipping charges for standard shipping. We will ship via Priority Mail for $12.00 per order (Save on multiple-book orders!). This may be reduced if actual postage is less than for a medium flat-rate box. INTERNATIONAL SHIPPING: In most cases, shipping via Biblio's consolidated shipping program via Asendia is the cheapest option on orders up to 5 lbs. International shipping rates are complex (cost depends upon weight and destination), so please feel free to email us for a quote before you order. If the actual cost of shipping is more than the automatically quoted rate, you must approve the additional charges before the order will be shipped. Shipping charges will be reduced if shipping weight is under 3 lbs. All shipping charges (except via Asendia) include 17% to cover Biblio fees and commissions that apply to these charges. LIBRARIES: We offer flexible terms to public and university libraries.
