"While moving around in this imaginary space
the philosopher makes written descriptions of the scenery
from different positions and in various directions. These notes
or sketches form a topography of the landscape. Before the philosopher
arrives at the final order of the published book, he selects, alters,
and rearranges this material."

Gunnar Liestøl, "The Reader's Narrative in Hypertext'" (Hyper/Text/Theory, 1994)
