This essay analyzes the functioning of a text that was designed to be read in a private context, that uses the computer as an active tool during the reading, and that can be published on a permanent medium such as CD-ROM. The work is approached in its dual functioning mode: synchronic and diachronic. A functional model is proposed, which involves an analysis of the functions that operate in the communication process between the reader and the author. In this model, the work appears as a process and no longer as an object. The reading and the materialization of the object read become interdependent. The author analyzes the relationships between readability and faithfulness in the resulting work, properties that may be incompatible in the final text.
