An anthology used in Tennessee schools changed “By God!” to “By gum!” and “My God!” to “You don’t mean it.” The New York State Education Department omitted mentioning Jews in an Isaac Bashevis Singer story about prewar Poland, or blacks in Annie Dillard’s memoir of growing up in a racially mixed town. California rejected a reading book because The Little Engine That Could was male.
