A bestseller is a book that is identified as extremely popular by its inclusion on lists of currently top selling or frequently borrowed titles that are based on publishing industry and book trade figures and library circulation statistics and then published by newspapers, magazines, or bookstore chains. Some lists are broken down into classifications and specialities (number one best selling new cookbook, novel, nonfiction, etc.). The New York Times Best Seller list is one of the best-known bestseller lists for the US. The New York Times Best Seller list tracks National and Independent book stores, as well as sales from major Internet retailers such as Amazon and Barnes & Noble. Other well-regarded lists are published by Publishers Weekly and the Washington Post.In everyday use, the term bestseller is not usually associated with a specified level of sales, and may be used very loosely indeed in publishers' publicity. Books of superior academic value or literary merit tend not to be bestsellers, although there are exceptions. Lists simply give the highest-selling titles in the category over the stated period. Some books have sold many more copies than current "bestsellers", but over a long period of time.Blockbusters for films and chart-toppers in recorded music are similar terms, although, in film and music, these measures generally are related to industry sales figures for attendance, requests, broadcast plays, or units sold.Particularly in the case of novels, a large budget and a chain of literary agents, editors, publishers, reviewers, retailers, librarians, and marketing efforts are involved in "making" bestsellers, that is, trying to increase sales.Steinberg defined a bestseller as a book for which demand, within a short time of that book's initial publication, vastly exceeds what is then considered to be big sales.
