Reading on paper still preferred

Anne Mangen from the University of Stavanger (Norway) explains in her blog on drupa.com why younger people still prefer to read paper rather than on screen.
We are very used to reading on a screen because of social media and email. Actually, we read more now than in paper only times. With the introduction of e-books trendwatchers predicted the end of the paper book. But they were wrong. How is it possible that the printed book is still popular?
Remarkable, says Mangen, because the paper book has many disadvantages compared to the e-reader: it is heavy and you need light to read by. But many readers prefer the printed book. Especially reading longer or complex texts is easier on paper. Shorter text, such as social media messages is easier digitally. Print and digital serve different, but complementary, purposes, according to Mangen.
