Orson Scott Card's Shadow of the Giant emerges as the hardcover on the most lists currently, debuting this week on the Washington Post list and remaining on 3 others. Previous leader State of Fear by Michael Crichton drops off 2 lists this week, to remain on only 2 others. (In paperback, Audrey Niffenegger's The Time Traveler's Wife remains on 5 lists.) Matthew Stover's Star Wars novelization Revenge of the Sith, remains on 2 Amazon lists with pre-publication orders. Mysteriously, Haruki Murakami's Kafka on the Shore, which ranked #1 on San Francisco's hardcover fiction list each of the past 3 weeks, disappears from the list entirely this week. J.K. Rowling's forthcoming Harry Potter and the Half-Blood Prince ranks #1 on the all Amazon lists. (Bookmark this link, Locus Online Bestsellers, for automatic redirection to the latest week's chart.)

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.
