The economic requirements of print technology produce various kinds and forms of edges:

• Books are experienced as separate, with edges and borders

• The need to create audience leads to standardization of grammar and spelling, which in turn support nationalism (i.e., edges and borders of language ---> edges and borders of geographical areas).

• The need to protect investments of author, printer, and publisher produces legal fictions of creativity and originality (i.e., edges and borders of the self in relation to community).

Print infotech radically changes cultures of orality and is in turn radically changed and challenged by digitality.
