Amazon publishes RSS feeds.

From Amazon’s Web Services Newsletter #3…

Amazon now provides RSS feeds for many browse nodes. These feeds were
built using AWS and XSLT. You can find convenient “builders” for the
feed URLs at several locations including
http://www.onfocus.com/bookwatch/AmazonRSS.asp and
http://www.neopoleon.com/blog/chooseFeedGroup.aspx .

For more information about Amazon’s feeds visit
