A dynamically updateable graphical index for rapidly scanning through content available on a website. The index comprises user-selectable levels within branches of a hierarchical tree structure representing various categories and sub-categories of content available on the website. All content on the website is associated with meta-data. The categories and sub-categories correspond to this meta-data. As content is added to the website, the content's associated meta-data is dynamically incorporated into the index and is searchable within the hierarchical tree structure displayed to the user.
