This document discusses theories of textual materiality and cybertext. It addresses how texts can be considered embodied entities through the interplay between their physical/material aspects and signifying strategies. Materiality is presented as a dynamic quality emerging from the relationship between a text as a physical artifact, its conceptual content, and the interpretive activities of readers. The document also discusses how cybertexts can be considered systems involving the text, a medium, and a human operator, with blurred boundaries between these elements. Game-like and narrative qualities of cybertexts are addressed, as well as how the reader takes a player-like role in interacting with such texts.
