On the other hand, I have paperback books I loved as a kid that were my father's when he was a kid. I carefully saved them for decades. One more generation and they could be considered family relics or something. I quickly realized the flaw with this plan as I tried to share them with my kids, who cannot be expected to treat brittle middle-grade and young-adult novels as museum pieces.

I am not entirely ready to part with the books, but I'm also unable to bear watching them get thoughtlessly destroyed by my kids. Digital has made it very easy to get copies of all of them; plus others I didn't manage to hold on to.
