This cell color indicates rankings on children's bestsellers lists		This cell color indicates rankings of books based on pre-publication sales				[Italics and brackets, and/or this cell color, indicate stale data -- rankings from one or more weeks before -- and do not contribute to the cumulative weeks on any list totals]

Key:
The table shows the current rank of each book and the change since last week, where:
   =    same as last week
   + or - with number:    difference since last week
   +    back on list
   ++    new on list
   x    no longer on list (number of x's: weeks off list)

All lists rank hardcovers and paperbacks separately, except for the USA Today list, which is a single list combining fiction and nonfiction in all formats, and BookScan, which combines hardcovers and paperbacks within lists for fiction, nonfiction, and children's. Dates shown are posted dates, except those in parentheses, which are dates compiled. New York Times posts its list one week in advance of print publication.

Note that some sources do not compile paperback bestsellers, and some exclude YA books (like the Harry Potter series) from their hardcover and paperback fiction lists.
