Julian Baggini, Financial Times – [snipped] “E-reading is certainly on the rise. The Pew Research Center reports that, as recently as 2010, hardly anyone in the US had an e-reader or tablet. Now half do. The proportion of the population who have read an ebook in the past year rose from 17 per cent in 2011 to 28 per cent just three years later. In the UK, figures from Nielsen, which monitors book sales, showed that one in four consumer titles bought in 2013 was an ebook, up from one in five a year earlier. Is this cause for concern? There is some evidence that reading on screen can result in less comprehension and even affect sleep patterns. But the research here is complex and inconclusive and, in any case, it is actually doing something far more interesting than telling us which medium is superior. It’s making us think more about what it means to read. As researchers examine the differences reading in different media make, they are also having to distinguish carefully between the different things that we do when we read. Take, for instance, the difference between “deep reading”, when you really get immersed in a text, and “active learning”, when you make notes in margins or put down the book to cross-reference with something else.”
