Radio Open Source — on public radio and the Internet — is an open, independent, not-for-profit project in “American conversation with global attitude,” as we call it. It is the invention of journalists Christopher Lydon and Mary McGrath, who own the contents and manage this site. Open Source represents by now nearly 20 years of the Lydon-McGrath collaboration with a far-flung network of loyal enthusiasts in an interactive discourse about arts, books, ideas and politics. Tax-deductible contributions to Open Source go toward re-launching and expanding the leanest little operation in home-grown non-commercial media. Help us grow the network, please, with comments, contributions and ideas. Thank you!
