Hypertext Writing hyperdocuments is a lot more difficult than writing text, because the author must make sure the reader is able to absorb the information in the text as well as in the structure of the hyperdocument, without encountering the difficulties described in the section on navigation. Apart from writing hypertext there is a whole research area devoted to the conversion of text into hypertext. We describe authoring tools for this conversion and for the creation of new hypertextual material a number. Each link should serve a clear purpose. Synonyms are encouraged as long as they are kept track of.
Visual layout is very important in screen design.
Minimize the burden on the user's short-term memory. Do not require the user to remember things from one screen to another. As the hyperdocument grows changes become more difficult to make. Authoring can sometimes not be distinguished from reading. Many hypertexts are used for sharing messages and documents between a group of users.
