University of Pennsylvania: PENNsound, writing.upenn.edu/ pennsound and Kelly Writers House webcasts. A stellar project at Penn, PENNsound is “committed to producing new audio recordings and preserving existing audio archives.” Here you can listen to readings from 1950s to today and often find great extras and links to other exciting websites. You can also link through to the Kelly Writers House webcasts at writing.upenn.edu/wh/webcasts and watch readings and craft talks with major contemporary poets and writers.
