The term navigation is used in the context of electronic
information systems to describe the processes and
means by which readers can move between
information nodes and gain some sense of their
orientation within the overall structure. Thus there are
two main aspects to navigation, one deals with having
a sense of location, orientation, and the other a sense of
how to change to a specific location, travel.

A good analogy to describe these two terms is to
consider a traveller using a subway system in a foreign
city. Once in the subway system, the traveller needs to
have some sense of where he or she is in relation to the
overall system. Once the traveller has this orientation,
there is also a need to be able to know how to move to
certain places. This involves such knowledge as where
lines intersect, how transfers are affected, how tickets
are purchased and how much they cost. A map                  Figure 6 A Page Index

One important issue about copyright that needs to be
understood is that copyright only protects the materials
themselves and not the ideas they contain. For
example, a person breaches copyright when he or she
reproduces using a photocopier or scanner or camera a
musical score. Copyright is not breached if the musical
score if reproduced by a hand copy. The reason is that

                                                           is not the image but the ideas.

The Web is one form of intellectual property and the
copyright rules apply to the Web and the underlying
materials as it does to others. One grey area of Web
copyright activity that is currently a copyright issue
relates to linking.
