This past weekend marked the fifth annual Brooklyn Book Festival. And although Sunday's weather was less than cooperative, it didn't stop booklovers including the very young ones from coming out to see their favorite authors. More than 200 authors participated, and on the children's and young adult side, that included Rebecca Stead, Jon Scieszka, Lauren Oliver, Francisco X. Stork, Chris Raschka, Mitali Perkins, Matthew Reinhart, and many more. Here, we present a gallery of photos from the festival's many panels, signings, and readings.
