Surfing the web by site.

We provide a system for surfing the web at a high level of abstraction, which is an analogy of the web browser, but which displays entire sites at a time. It allows a principled investigation of what is present, based on an overview of all available information. We show a site's relation to other sites, the broad nature of the information contained and how it is structured, and how it has changed over time. Our current system maintains a continuously updated archive of 40 million sites representing 1.9 billion web pages, and enables real-time navigation through the sea of web sites.
