How often are the online catalogs updated?
Our website catalog data are updated weekly. Pricing and availability are updated nightly. The catalog information reflects the best information available at the last update. Please note that publication dates and prices are subject to change without notice. Prices in the catalogs are stated in US dollars and valid only for sales transacted on the US webserver. Not all titles are available for sale outside the United States. If you see an error on a catalog page, please contact the webmaster and the information will be updated in the master record as time permits – usually, by the next catalog build.
