As with most Web 2.0 sites today, Barnes and Noble uses a "MY" section on their website for regular visitors and those who have purchased before. This section resides at the very top of the screen and includes "My Barnes and Noble", Store Events and more. Again, they are staying with the theme that many popular websites use: provide a personalization aspect to your site so that customers feel like a part of the process (rather than someone who just stumbled upon the site).
