It's Friday--Book Business Day. In the current online edition of Publishers Weekly there's a page with a selection of articles all about the children's side of the book business under "industry news." Just like a buffet, you can take your pick--read about who's fired and who's hired, or about PEN World Voices 2010, or Spider-Man at Little, Brown. It's a great place for news-ten articles--dig in! Check it out here.
