Barnes & Noble began as a college book emporium. Now, this huge company sells virtually every new book you can think of. There are more than a dozen Barnes & Noble stores in Manhattan alone, including this superstore. Textbooks are still a strong point at the Union Square location, as are volumes from the great literature of the world, paperbacks and children's books. Seating is available, and authors frequently put in an appearance to sign their latest creations. Most branches have a cafe as well as an extensive magazine section.
