A few children's classics made the cut in the Boston Globe's recent list of 100 "essential" books either about New England or written by an author with ties to the region.
Little Women (#2)
Make Way for Ducklings (#3)
Charlotte's Web (#15)
Mike Mulligan and His Steam Shovel (#54)
The Very Hungry Caterpillar (#100).
Avid readers could make a case for lots of others, like anything by Dr. Seuss (born in Springfield, Mass.), Where the Wild Things Are (Sendak lives in CT) Barbara Cooney's Miss Rumphius, Donald Hall (author) & Barbara Cooney's (illustrator) Ox-Cart Man, Candace Fleming's The Great and Only Barnum (not to mention many other biographies of famous New Englanders), and The Story of Ferdinand (illustrator Robert Lawson was a CT resident).
