@Edent I did much the same thing as you! And I still largely read on my phone or kindle or listen to the audiobook. But I also have acquired mostly a lending library of academic books associated with my field. And to be honest I’m less worried about the apocalypse than I am about Amazon suddenly pivoting to something else and discontinuing support for its e-books a la Google, or removing them from my library if a publisher withdraws a deal a la TikTok music.
