The affordances of computer-based texts, such as hypertext, windows, articulation of audio with text and image, and the inclusion of dynamic images, have fundamentally transformed many of the literacy practices derived from interaction with conventional texts. This means people need to reconceptualize the ways in which text form relates to text comprehension and composition. However, although there is no doubt that multimedia, electronic, information sources are quickly taking up the communication of much information previously presented solely in traditional text formats, this has not meant the extinction of conventional literacies. Rather, they are maintaining a complementary role as well as being both co-opted and adapted in the evolution of their textual habitat. To understand the contrasts, continuities and complementarities of literacy practices entailed in using texts in conventional and digital electronic formats, research is needed on the nature of the relationships among the rhetorics of electronic and conventional, texts and the comprehending strategies readers need to use. A first step is to investigate how the rhetorical organization of conventional texts relates to their rhetorical organization in digital electronic form. Three key parameters of such an investigation are the organizational structuring of the written texts, the nature and role of images, and the rhetorical use of hypertext within digital electronic formats. This paper focuses on the latter two parameters.
