Bookshops in boxes may not seem that charming on the surface, but when this particular setting is considered, hello enchanted book-buying. Why? Because these boxed-up bookshops line the banks of the river Seine in Paris; on the right bank from the Pont Marie to the Quai du Louvre, and on the left bank from the Quai de la Tournelle to Quai Voltaire. Stretching for almost 2 miles along the world’s most romantic river, there are 900 green boxes from which 240 “bouquinistes” offer some 300,000 old books and other assorted paper ephemera. Can you say, “j'adore”?
