My position is straightforward. I infinitely prefer a hard-cover book. I am happy to use the internet for research and investigation but nothing gives the same pleasure as sitting with a well produced book. My problem is cost. Many high quality aviation books are, for me, very expensive, so I have to be very selective. I am not in any way suggesting that the books are overpriced, such are the costs of high quality production these days, but I wonder if that is one reason for the contracted market.
