Any bookish person who has ever passed through an airport in the United States will tend to have been struck by a contrast. Airport bookshops in the UK are piled high with thrillers, spy stories, romantic comedies and how-to books: untaxing fare for a long flight.
But in the States, which we Brits like to sneer at as the lowbrow land of Walt Disney and Man Vs Food, those airport bookstores have a really striking amount of hefty hardback nonfiction: thumping great presidential biographies, weighty works of serious history, chewy books of business theory and popular science.
