Yet research has already told us a lot about how we read now. First and foremost, it emphasises that even using paper, there are many different approaches. Most of us probably have a settled style: you might be a skimmer, a skipper, a front-to-back completist, a keeper of the pristine page or an obsessive writer of marginalia. Whatever the case, our habits have probably been created largely as combination of childhood experience and how the medium we read in is nudging us.
