O'Reilly - Amazon Hacks
In Amazon Hacks, Paul Bausch documents most of the avenues Amazon.com has opened up for exploration of the database. A lot of his coverage borders on the obvious: Sections on how to "Power-Search for Books" and "Put an Item Up for Bid at Amazon Auctions" aren't too different from Amazon's own explanatory articles. Coverage of how to add an Amazon search box to your own site, and add Amazon Associates item links to various kinds of Weblogs (including Blosxom and Moveable Type) are much handier. Bausch really shines when explaining Amazon.com's Web Services (AWS), the remotely accessible software interfaces that enables programs to search the database.
