Librarians and publishers proved a hardy bunch at this year’s American Library Association annual meeting, held June 26 to July 1 in Las Vegas, where temperatures climbed a high as 110 degrees. But the heat didn’t stop the multitude of authors and illustrators in attendance from mingling with librarians and signing copies of their books. The Newbery-Caldecott banquet bestowed the industry’s top honors to this year’s winners, Kate DiCamillo and Brian Floca, as well as the Honorees. Here we present some of the photographic highlights from the exhibit floor.
