Best-seller lists for books are available from major news publications, such as the New York Times, and from bookseller websites, including Amazon.com. Some lists are genre- or format-specific, while others are a broad overview of current bestsellers.
The New York Times, USA Today and Publisher's Weekly are three of the most popular best-seller lists. The website for each contains a variety of more specific lists, including fiction, nonfiction, genres and age-specific books. In addition, these sites provide book reviews to help readers decide on their next purchase. Each publication updates its lists once a week.
Amazon.com and Barnes & Noble also have best-seller lists based on their own sales data. These lists are updated hourly and are more comprehensive than the traditional lists.
