Mary Norris has a gift for your favorite grammarian in this week’s New Yorker: a detailed account of comma policy from a veteran copyeditor. The magazine is notorious for its meticulous house style (where else do you still see a diaeresis over the word coördinate?), which it owes to Mensa-level punctuator Eleanor Gould and her acolytes. The piece offers a fantastic glimpse into the magazine’s culture, and gets to the philosophical roots of the punctuation debates. As Norris sees it:
The New Yorker isn’t asking you to pause and gasp for breath at every comma. That’s not what close punctuation is about. The commas are marking a thoughtful subordination of information.
