Yes! Physical books aren't important, it's the ideas they contain that are the valuable, need-to-be-preserved things. So says Wachtell, and I agree. She says that long-form texts (or lofty ideas) are the driving force behind publishers and often readers, and that no matter what format they are delivered in, they are vital to us because they make us think. But, as Machtell points out, they are not cheap. That's where the danger lies--people want to pay less for books, but the cost remains the same as far as the contributors to that book are concerned.
