Best Sellers - The New York Times A version of this list appears in the December 20, 2009 issue of The New York Times Book Review. Rankings reflect sales for the week ending December 5, 2009. An asterisk (*) indicates that a book's sales are barely distinguishable from those of the book above it. A dagger (†) indicates that some retailers report receiving bulk orders. Rankings reflect sales reported by vendors offering a wide range of general interest titles. The sales venues for print books include independent book retailers; national, regional and local chains; online and multimedia entertainment retailers; supermarkets, university, gift and discount department stores; and newsstands. E-book rankings reflect sales from leading online vendors of e-books in a variety of popular e-reader formats. E-book sales are tracked for fiction and general nonfiction titles. E-book sales for advice & how-to books, children's books and graphic books will be tracked at a future date. Titles are included regardless of whether they are published in both print and electronic formats or just one format. E-books available exclusively from a single vendor will be tracked at a future date. The universe of print book dealers is well established, and sales of print titles are statistically weighted to represent all outlets nationwide. The universe of e-book publishers and vendors is rapidly emerging, and until the industry is settled sales of e-books will not be weighted. Among the categories not actively tracked at this time are: perennial sellers, required classroom reading, textbooks, reference and test preparation guides, journals, workbooks, calorie counters, shopping guides, comics, crossword puzzles and self-published books. The appearance of a ranked title reflects the fact that sales data from reporting vendors has been provided to The Times and has satisfied commonly accepted industry standards of universal identification (such as ISBN13 and EISBN13 codes). Publishers and vendors of all ranked titles conformed in timely fashion to The New York Times Best Seller Lists requirement to allow for independent corroboration of sales for that week. Publisher credits for e-books are listed under the corporate publishing name instead of by publisher's division. Sales of both print books and e-books are reported confidentially to The New York Times. The Best Seller Lists are prepared by the News Surveys and Election Analysis Department of The New York Times. Royalty Share, a firm that provides accounting services to publishers, is assisting The Times in its corroboration of e-book sales.
