To make this guide, we surveyed more than a hundred authors, illustrators, librarians, booksellers, academics, and publishing pros. We ended up reading more than 200 books, for which we must fulsomely thank our local libraries. Our goal: to find the books that represent the best of these transformations, and to tell the story of an art form that responded to a front-page crisis with a new wave of inventive stories that respect the intelligence, playfulness, and widely differing experiences of young readers. With each entry, we’re suggesting a few other, similar picture books also admired by our nominators—as well as a collection of similar books for older kids, read-alikes suggested by the children’s lit experts at the public library in Arlington, Virginia.
