CASCADE provides multiple tools to support navigation and information finding. The tools may be thought of as a set of maps at different scales which can be used together to aid movement through complex, abstract document spaces. We begin with the assumption that documents and document components are objects, these objects are related and have attributes. Each tool looks at one or more of these features. The tools currently implemented for CASCADE beyond the traditional navigation tools such as bookmarks and history lists are Docuverse, Webview, Landmarks, and Preview.
