I agree, I'd even go so far and say it's one of the best places on the internet to discuss 'serious' books (within all the rampant troll posts). Book discussions on reddit are far too positive when it comes to terrible books, /lit/ will call a bad book a bad book. Plus there was always an undercurrent in interest in 'obscure' books - there are great reading charts out there for all kinds of literatures and languages made by /lit/ users.
