Two providers have been set up using this protocol for you. In order to use the Amazon provider, you must sign up for a free Amazon AWS account, and enter your Access Key Id Secret Access Key. You can find these "Access Identifiers" under the link to "Your Account" on the AWS website. Previous versions of &app; included an Amazon AWS Access Key ID. From August 15 2009, Amazon have changed their "Product Advertising API" so each request must be authenticated, requiring a Secret Access Key. It is not possible for us to distribute secret keys to users. So, in order to continue using the Amazon provider you will need to sign up for your own free AWS account. You don't require an Amazon AWS account in order to use &app;'s other providers. So, if you don't want to sign up for an AWS account, you can leave these settings blank, and &app; will simply not search Amazon when looking up books. &app; can download book information from different amazon websites - currently, amazon.com, .co.uk, .fr, .de, .ca and .jp . To change which site to use, select Amazon from the Provider list, and click on Setup. Then choose either ca, de, fr, jp, uk or us from the drop-down menu. &app; can search the Proxis website for books in either English, French or Dutch. To change which language to use, select Proxis from the Provider list, and click on Setup. Then chose either en, fr or nl from the drop-down menu.
