Amazon has introduced a weekly best seller list that ranks books by what readers are actually reading — not just what they’ve bought.

The new list, called Amazon Charts, also has a most-sold component that incorporates sales of its Kindle e-books and audio, as well as print books.

The Seattle company had long posted lists of book sales by the hour but the weekly lists are new and reflect the increasingly complex trove of data about users’ habits Amazon has available to it from its e-commerce site and other connected apps — including audiobook purveyor Audible, the GoodReads social recommendation service, and its Kindle e-books app. The lists also sharpen the rivalry with other best-seller lists, such those at USA TODAY and The New York Times.

“This won’t supplant the (New York) Times — or USA TODAY for that matter — but it will definitely add a lot of interest because it measures things a different way and the ‘compare and contrast’ gene will kick in for many observers,” said Mike Shatzkin, founder and CEO of Idea Logical Company, a publishing industry consulting company.

Amazon’s “Most Read” list comes from Kindle ebooks and Audible audio books, but doesn’t include paper books. It ranks books by the average number of daily Kindle readers and daily Audible listeners each week, whether they are in the process of reading or have completed reading the book in that week, the company said.

The “Most Sold” list ranks books based on the number of print and electronic copies sold and pre-ordered through Amazon.com, Audible.com and Amazon Books brick-and-mortar stores as well as books borrowed from Amazon’s subscription programs such as Kindle Unlimited, Audible.com, and Prime Reading.

Amazon is also leveraging other data it has about the American book-buying public’s habits. That includes lists which books are most anticipated, based on the rate of customer pre-orders and which Kindle books “were simply Unputdownable,” according to how quickly customers read them from cover to cover.
