This week, Amazon revealed the location of its second brick-and-mortar bookstore, which will open in a few months in Southern California, at a mall near the University of California, San Diego. The online retailer seems to have big ambitions for its physical stores. On Wednesday, Nick Wingfield, who covers Amazon for The New York Times, visited the only Amazon bookstore in existence, in the University Village mall in Seattle. From inside the store, he had an online chat with Alexandra Alter, who writes about publishing for The Times.
