USA Today reports that the National Book Award winners are seeing increased print runs by publishers. Here are some of the book and the news print runs from the publishers.
Jeanne Birdsall's The Penderwicks (young people's literature winner) -- 20,000 additional copies being printed by Random House
Joan Didion's The Year of Magical Thinking (nonfiction winner) -- new print run of 50,000 from Knopf
William T. Vollmann's Europe Central (fiction) -- 35,000 new copies from Viking
W.S. Merwin's Migration (poetry) -- has received orders for 12,000 more copies and has sold 9,000 copies
Those are some good-sized print runs. Clearly, the National Book Award has an extra benefit in addition to the $10,000 prize and the increased recognition winning authors receive.
