According to me, there are three criteria that would make something a classic - literary quality,historical significance and experimenting styles. In a way, this word Classics is a bit unhelpful; on the one hand it suggests status and quality and on the other hand it sort of implies old, dull, dusty and difficult books that you struggled through at school. I think it’s a double-edged sword. There were old, boring books but there’s a reason they’re long forgotten, they haven’t survived. The classics that have survived and that we publish are still being read because they are different and controversial and dangerous sometimes.
