“This isn’t, Mr. Petrilli says, a list of the greatest picture books in history. It’s a list of the books you must know, like “Goldilocks and the Three Bears.” “There are plenty of children’s stories more compelling, in my opinion,” he writes. “But if you’ve never read Goldilocks, you’ll miss myriad references in literature, pop culture, newspaper editorials, and so forth. Which makes Goldilocks a must.” - × × ×
