Because readers seldom read long passages online, hypertext writers
must create short, self-contained topics that do not require any
particular sequence to be understood.
To create short, self-contained topics:
Write topics that address only one main idea.
One sign of a clearly focused topic: it answers one question about
one subject for one purpose. According to William Horton (1994),
"The question may be general or specific, the subject may be concrete
or abstract, and the purpose may be global or localbut all are
clearly defined" (p. 104).
One way to ensure coherence in a topic is to first write a single
question that the topic is meant to answer. Then, judge whether
the topic fully answers that question.
Keep length to a minimum.
Horton (1994) warns that readers will not read more than three
windows or screens of information to answer a question. Thus,
he recommends that each topic contain only one-third to one-fifth
of a paper page.
To help keep length to a minimum, you can "cross-reference rather
than include" (Horton, 1994). For instance, you need not explain
each new term, concept, or acronym where it is introduced. Instead,
provide this information via hypertext links.
Write, edit, and review topics in random order.
This strategy helps to ensure that your topics can be read in
any order and still be understood.
Use storyboards to create topics.
Kathleen McCabe (1997) recommends using storyboards since the
view of a hypertext document is narrowed to a single screen. This
practice helps to ensure a suitable and accessible organization
for readers.
Repeat contextual information as needed to counter loss of context.
To counter the loss of context, repeat contextual information
each place it is needed and provide links to related information.
For instance, contextual information can explain where the topic
fits within the larger body of information.
