The document describes Lawrie Hunter's information structure maps (ISmaps) which are used to analyze and represent the structure of information in texts. The ISmaps identify and represent key information structures such as description, classification, comparison, sequence, and cause-effect. Examples are provided of how Hunter's ISmaps can be used to break down texts and diagrams according to these different information structures.
