Saw this in today's Shelf Awareness:
"Poof. For the first time since 1998, there are no Harry Potter titles on the New York Times (Times) noted. The Harry pileup on the hardcover fiction list led to several changes of the paper's bestsellers, including the creation of a separate children's list."
Amazing! For 10 years, there has been a Potter presence on the List. Say what you will about Harry but that's quite a literary and cultural achievement.
