Two book podcasts I listen to regularly.
CBC Writers & Company
Eleanor Wachtel is probably the finest interviewer of writers out there. Give a listen to her recent interviews. In one of the episodes, Orhan Pamuk is interviewed and what he said about V S Naipaul is still on my mind. Naipaul, Pamuk says, sought the center of colonizers to understand his own place while he (Pamuk) does not feel the need to go out of Turkey (Pamuk rarely goes out of Istanbul) since Turkey was never colonized. In another episode, Arthur C Clarke is interviewed. Mind filling.
World Book Club
Another podcast that is a great place to spend your time.
