The fact of the matter is that net sales of hardback and paperback books have held relatively steady for the past 5 years

AAP report: book sales down 2% in first 9 months of 2015; eBook sales down 11%.  (Talking New Media, 1/27/2016)

The articles stresses that the American Association of Publishers does not report on sales of all ebooks.  Its focus is generally on larger, established, American publishers as opposed to small presses and self-published materials.

This caveat, of course, will not stop the ongoing brouhaha over the actual sales of ebooks.

It is, perhaps, instructive to note the AAP reports that sales of children's/YA ebooks for January-September 2015 are down 44.8% from the comparable period in 2014.  Paperbacks, on the other hand, are up 13.3%.

Bottom line:  People are still reading print in mass quantities.
