Enough of these tracts about there being too many books published and too few classics, writes Robert McCrum. “In an age of rampant capitalism, in the middle of a colossal information-technology revolution unparalleled since Gutenberg, it would be surprising if there was not a colossal overproduction. No more classics? Possibly the hyperactivity of the marketplace makes good books harder to detect, but there’s no evidence that good books are missing their audiences or that writers today are any worse, or any better, than 50, even 100 years ago.”
