Text headings can be used to structural and expressive advantage in technical material, increasing textual coherence and encouraging reader/text correspondence. The five general types of headings are differentiated by their functions: (1) descriptive headings refer to the most prominent feature of a text section; (2) reflective headings provide identification or author commentary; (3) narrative headings mark the progress of the subject and may tell its story in condensed form; (4) rhetorical headings generally present an allusion or veiled argument; and (5) absent/implied headings refer to texts either without headings or minimally subdivided. Computer software and other more traditional media may also be improved through more effective division of the whole into parts. (MM)
