As of this week, the archive of this show is behind a paywall. The three most recent episodes are free, but earlier episodes are available only to New York Times subscribers. If you don’t want the whole subscription, there’s an audio-only subscription for $1.50 a week. That gets you access to our archives, as well as the archives of all the other great Times podcasts.To help make the pitch here, I wanted to share an episode from our friends at the “Book Review” podcast. It’s hosted by Gilbert Cruz, the editor of The Times’s Book Review section. And I thought you might enjoy this particular episode with Robert Caro about his book “The Power Broker.” It came out 50 years ago, and it’s still one of the most influential books in politics and policy circles — for better or for worse. In this conversation they dig into why that is and what to make of the book’s legacy. I hope you enjoy it. To learn more about the subscription, visit nytimes.com/podcasts. Soon, you’ll need a subscription to maintain access to this show's back catalog, and the back catalogs of other New York Times podcasts, on Apple Podcasts and Spotify.
