But in our living room we have two big inset shelves where I keep all the books I feel like I need or want ready at hand. And last night, sitting in front of them, I had this dark epiphany. How much longer are these things going to be around? Not my books, though maybe them too. But just books. Physical, paper books. The few hundred or so I was looking at suddenly seemed like they were taking up an awful lot of space, like the whole business could be dealt with a lot more cleanly and efficiently, if at some moral loss.
