That is interesting ftorres. I wonder if the re kindled interest in paper books is due to savvy shoppers who are finding both hard cover & paperback books at bargain prices in discounted stores, not book stores. The increased price for the same title in eBook. I have noticed these books by popular authors, like Stephen King or Spencer Quinn in discount stores sold New, not their latest book, but still they selling at a fraction of the eBook price.
I almost never read paper books anymore, but I can certainly understand the appeal of discounted paper books. I am getting tempted by the prices especially in hard cover.
