Mary Norris has spent more than three decades in *The New Yorker* ‘s copy department, maintaining its celebrated high standards. Now she brings her vast experience, good cheer, and finely sharpened pencils to help the rest of us in a boisterous language book as full of life as it is of practical advice. *Between You & Me* features Norris’s laugh-out-loud descriptions of some of the most common and vexing problems in spelling, punctuation, and usage—comma faults, danglers, who vs. whom, that vs. which, compound words, gender-neutral language—and her clear explanations of how to handle them. Down-to-earth and always open-minded, she draws on examples from Charles Dickens, Emily Dickinson, Henry James, and the Lord’s Prayer, as well as from *The Honeymooners* , *The Simpsons* , David Foster Wallace, and Gillian Flynn. She takes us to see a copy of Noah Webster’s groundbreaking Blue-Back Speller, on a quest to find out who put the hyphen in *Moby-Dick* , on a pilgrimage to the world’s only pencil-sharpener museum, and inside the hallowed halls of *The New Yorker* and her work with such celebrated writers as Pauline Kael, Philip Roth, and George Saunders. Readers—and writers—will find in Norris neither a scold nor a softie but a wise and witty new friend in love with language and alive to the glories of its use in America, even in the age of autocorrect and spell-check. As Norris writes, The dictionary is a wonderful thing, but you can’t let it push you around.
