Politico has done a story about those now rather infamous Clinton campaign conference calls. The piece includes a survey of greatest hits (my favorite: a silence long enough to "knit a sweater" according to Time's Mark Halperin when Slate's John Dickerson asked exactly what foreign policy experience Hillary Clinton had that made her qualified to answer that 3 am call). And gives a general overview of how they evolved and how they are used.
And if you want to listen to the calls yourself, here's a site that posts them for the public.
I love the internet.
