Traditional rules emphasize the utility and intentional coherence of a text.
They direct scriptor's' attention to points of arrival and departure, arguing that they must decide what readers need to know at either end of a hypermedia link in order to make use of what they find there. To determine what users need to know, the author must assume some unified or teleological understanding of the text !
In much the same vein, they contend that hypertext presentations need to preserve contextuality and provide a means by which the user can see the fragment's place in the coherent whole. The complexity and multiplicity of the hypertext, a complex system of documents and exhibits, reduces at some conceptual level to a unified body of information, a training manual or a course text. According to traditional views, while it is true that this hypertextual material could not be presented as effectively in a book, the difference is of degree not of kind.
