This is the 2020 version of a very popular Goodreads list, which, as far as I can tell, was last published by Stephanie Winkler more than 5 years ago. Although hardly anything has happened in the real world since then, the relative positions of the books have changed considerably. Moreover this updated version is TWICE as long.
BTW, make sure you only tick the version of "1984" / "Nineteen Eighty-Four" that you have actually read (only joking, but because the two spellings appear separately on the list, Orwell's work might have been higher up the scale).
