What is this view?

You are using a dynamic assistive view of the National Science Foundation site. It has all the same data and features of the original site but formatted just with assistive users in mind. It has links and content reorganized to aid assistive users and has controls at the bottom under assistive options that allow you to control key aspects such as font size and contrast colors etc.
This is not a separate text-only site, it's a dynamic view that uses unique technology from Usablenet to give assistive users better, more accessible access to the same content and features as all users that use the graphic view of the site.
