    1. Hypermedia is a set of nodes of information (the “hyperbase”) and a mechanism for moving among them.

      Hypermedia consists of a set of nodes of information (hyperbase) and a mechanism for navigating between them.

      A book is the degenerate case where the nodes are the paragraphs and the topology is a linear chain.

    1. Overview diagrams are one of the best tools for orientationand navigation in hypermedia documents [17]. By present-ing a map of the underlying information space, they allowthe users to see where they are, what other information isavailable and how to access the other information. How-ever, for any real-world hypermedia system with many nodesand links, the overview diagrams represent large complexnetwork structures. They are generally shown as 2D or 3Dgraphs and comprehending such large complex graphs is ex-tremely difficult. The layout of graphs is also a very difficultproblem [1].

      Overview diagrams are one of the best tools for orientation and navigation in hypermedia documents.

      For real-world hypermedia documents with many nodes, an overview diagram becomes cluttered and unusable.
