In electronic text, which includes other media besides hypertext, the author still exists but as a designer, a choreographer.
The reader is not the author of the text but can experience many of the "exciting aspects of artistic creation - the thrill of exerting power over enticing and plastic materials" as Murray put it. The reader of electronic text, and especially hypertext, is not experiencing authorship. The reader is experiencing agency. Murray defines agency as the ability to take meaningful actions and to see the results of those actions. Murray points out that the kind of agency that takes place in the reading of hypertext fiction, particularly, is rather rare in more traditional narrative forms. The difference may be that by entering a computer environment, the reader alters the environment of the text through his or her participation.
