Both Amazon and PW appear to be stale this week -- unchanged since last week. PW used to post its Monday-dated lists on the prior Friday; now they're not appearing until Monday or later. This may be a glitch as they redesign their website, or a permanent change. Several new titles this week, on at least one list each: Harry Turtledove's American Empire: Blood and Iron and David Weber & John Ringo's March to the Sea are both runners-up on the NYT list; a Star Wars paperback novel by Greg Keyes debuts on the NYT and USA Today lists; the paperback of Stephen King and Peter Straub's The Talisman ranks on the same two lists; and the Harry Potter and the Sorceror's Stone Move Poster Book, with photos from the upcoming film, debuts on three lists this week. Update 16 August: PW's ranking for 13 August added.

This cell color indicates rankings on children's bestsellers lists						Italics indicates stale data -- rankings from one or more weeks before

The table compiles SFFH books placing on general bestseller lists. The table shows the current rank of each book and the change since last week are shown, 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)

Columns show ranks on lists from, respectively, New York Times, Los Angeles Times, San Francisco Chronicle, USA Today, Washington Post, Wall Street Journal, London Times, Publishers Weekly, BookSense, Amazon.com (fiction lists), and Amazon UK (fiction lists). 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.

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.
