For some documentation and discussion of the New Yorker magazine's curious aversion to quotative inversion, see "Quotative inversion again", 10/29/2009. And against that background, consider this sentence from E.B. White's 1957 piece "Letter from the East", quoted in my earlier post:
"Omit needless words!" cries the author on page 21, and into that imperative Will Strunk really put his heart and soul.
A careless slip of the red pencil? Or was E.B. White exempt from the dictum? Or was the no-quotative-inversion diktat imposed by a post-1957 New Yorker style maven? Perhaps someone who knows more about the history of that publication's quirks can tell us.
