I haven’t found a way to easily download the audio files (which is a shame) — but one can grab the transcripts through wget — some of the recordings are really hard to listen to, but it is Faulkner speaking about writing and reading his own work: Faulkner at Virginia.
(A propos de Faulkner, voyez la fin de ce billet pour en lire un extrait : Rien n’est jamais acquis)
