I am wondering if any studies have been done on screen reading versus print reading in terms of comprehension. I think it is one thing to read for pleasure on a screen but an entirely different matter to try to comprehend difficult matter online. I spend a significant part of the day reading online but I do know that if the subject is complex I absorb it much better on print. Given my age I wonder if this might be a generational issue/
