With the rise of mobile browsing, it's important for the site to be useful in a mobile environment. The site will now automatically scale itself to the size of the device you are using. If you're using a phone, the main navigation bar at the top will collapse and the navigation bar will be available through this icon at the top right of the screen.
Visitors using really old browsers will still be able to access the site, but it won't be pretty. Older browsers may not be able to show our search pages. I would recommend using the Google site search tool on the advanced search page. If you can't view that page then use Google to find what you're looking for. To find an author type "Nora Roberts FictionDB" into Google. You can then link directly to the page you are looking for.
Please let us know if you are experiencing any other trouble with the site.
