It’s the summer of children’s books in New York. The Society of Illustrators is celebrating the creative legacy of Maurice Sendak with an exhibition of more than 200 Sendak originals, and his beloved wild things can also be found rumpusing at the New York Public Library as part of “The ABC of It,” a show that examines why children’s books are important, what and how they teach children, and what they reveal about the societies that produced them.
