And more detail (bolding mine again):
"Each week, USA TODAY collects sales data from booksellers representing a variety of outlets: bookstore chains, independent bookstores, mass merchandisers and online retailers. Using that data, we determine the week's 150 top-selling titles. The first 50 are published in the print version of USA TODAY each Thursday. The top 150 are published online.
USA TODAY's Best Selling Books list ranks titles regardless of format. If, for example, Jane Austen's Pride and Prejudice sells copies in hardcover, paperback and e-book during a particular week, we combine sales from each format. In our list, following a title's description, we note which format recorded the most sales that week and the price of the book in that format.
Each week's analysis reflects sales of about 2.5 million books at about 7,000 physical retail outlets in addition to books sold online. Those reporting include: Amazon.com, Amazon Kindle, B. Dalton Bookseller, Barnes & Noble.com, Barnes & Noble Inc., Books-A-Million.com, Books-A-Million, Bookland and Books & Co., Borders Books & Music, Brentano's, Davis-Kidd Booksellers (Nashville, Memphis), Hudson Booksellers, Joseph-Beth Booksellers (Lexington, Ky.; Cincinnati, Charlotte, Cleveland, Pittsburgh), Powell's Books (Portland, Ore.), Powells.com, R.J. Julia Booksellers (Madison, Conn.), Schuler Books & Music (Grand Rapids, Okemos, Eastwood, Alpine, Mich.), Target, Tattered Cover Book Store (Denver), Waldenbooks."
