On February 11, 2011 The New York Times introduced best-seller lists including ebook (e-book) best sellers. They offered rankings of titles when print and e-book sales were combined, and also offered separate rankings for print and e-book titles in fiction and non-fiction categories, hardcover and paperback, etc.
"This week’s Book Review introduces revamped best-seller lists, the result of many months of planning, research and design.
"On the Web, there are three entirely new lists. One consists of rankings for fiction and nonfiction that combine print and e-book sales; one is limited exclusively to e-book sales for fiction and nonfiction; and the third, Web-only list tracks combined print sales — of both hardcover and paperback editions — for fiction and nonfiction.
All the other lists, though presented in reworked formats, will be familiar to readers. The Book Review’s related columns — TBR: Inside the List, Editors’ Choice and Paperback Row, all written by Book Review editors — remain in their accustomed places in print and online. We continue to offer extended rankings, a full methodology and a list archive online.
"As before, The Times’s News Surveys department, which directs the paper’s polling operations, including its political and election polls, will collect and analyze the data reflected in each list."
