The History List
Although systems offer a way to follow links backwards repeatedly,
so you can always get to a point you were before,
providing an overview of the nodes you visited before may help you in
getting an idea where in the hyperdocument you are.
There are two possible ways to implement a history list:
- A complete history list acts as a logfile, showing all (URLs or titles
of) nodes you visited before. Nodes may or may not end up twice in the
list when you visit them again, either by accident or by following links
backwards.
- An abbreviated history list only keep nodes from a "straight" navigation
path. When a user follows a few links forwards, then backs out and
starts following links in another direction, the "side track" is forgotten.
This is the way the history list works in most
WWW browsers for instance.
