In a bookstore, I saw a woman taking photograph after photograph of newly released titles that were arranged on a shelf. She was using her phone to take the pictures.

I didn't understand. Why would anyone want to take pictures of books?

Then, at a restaurant, waiting for a table, I heard two men, also waiting, talking. One said he had just ended a frustrating day at the store he owned.

"Do they think I'm a showroom?" he said.
