I’m studying and the Cold War and the Holocaust this upcoming year and if anyone can recommend some podcasts, or books or videos or movies on that, I would be most grateful. Best wishes!
For the Holocaust, I'd recommend Browning's Ordinary Men: Reserve Police Battalion 101 and the Final Solution in Poland.
The Behind The Bastards podcasr has a good two-part episode called How Nice, Normal People made the Holocaust happen which is worth a listen. They notably provide a full bibliography for each of their episodes online.
