Amazon

Aaron Shepard has unveiled the 'next generation' version of his excellent publishing tool Sales Rank Express, which provides a summary of information from Amazon for publishers on ten of their books (at a time):

It's now several times as powerful, with a lot more information presented, and a lot more convenience in looking for it. You can search by author, publisher, title words, ISBN (10-digit or 13-digit), or any combination of the four. Within the results, you can then automatically look up the same info for all formats of a title (paperback, hardcover, etc.), or for the book’s top ten pairings (the competing and complementary titles used for Also Bought lists, exit offers, etc.).

The new version provides information on sales rank, customer rating, Amazon discount, copies in stock and top pairings, plus lots more. Full details are available on Aaron's blog.
