“Mass market paperbacks, those pocket-sized best sellers available everywhere from airports to drug stores, are on the decline, apparent victims of increased competition and the squints of baby boomers who value larger print over lower prices.” So publishers are experimenting with a larger format. “The new paperbacks will be at least a centimetre taller than mass market books — big enough to make the books more readable, but small enough to fit into pockets and existing store racks. In both size and prize, they will stand midway between mass market books and “trade” paperbacks, which are the same size as hardcovers.”
