A podcast series usually focused on Popper and vicinity, but sometimes on Nabokov, features an episode where Brian Boyd talks about both, but mainly Nabokov. There's a lively three-way interaction.
my book about Nabokov and Germany - "Vladimir Nabokovs Eigenwelt. Deutsche Bezugspunkte einer russischen Künstlerexistenz" - was published on 16.05.2022 by Vandenhoeck & Ruprecht.
