David points us to the Montague Bookmill. This is the bookstore of the future, because it's not a business trying to maximize growth and ROI. No, it's a place, an attitude, an approach to an afternoon. They don't sell every book, they don't even pretend to.
Just as vinyl records persist, an object of joy for some listeners and a profitable cottage business for some sellers, bookstores are going to become like gift stores. The goal isn't a commodity transaction with maximum selection at minimum price, the goal is an experience worth seeking out and paying for.
We're going to see more and more of these newly archaic industries turn into lifestyle businesses, which is what they used to be before Wall Street showed up.
