‘Holy Writ,’ a glorious article by Mary Norris in the current New Yorker, is about commas, not Third Circuit advocacy.
But if you’re the sort who reads an appellate blog, there’s a good chance you’ll really enjoy it.
If an article is not enough to scratch your punctuation itch, Norris has a book due out in April, Between You & Me: Confessions of a Comma Queen. And if April is too long, I recommend Noah Lukeman’s A Dash of Style.
