Bolter

Jay David Bolter's book was the first major English language work that explicitly defined hypertext from the point of view of literary practice and theory.

This is a key work (though perhaps overshadowed by Landow's more explicitly critical "Hypertext: The Convergence of Hypertext and Literary Theory") that contextualises hypertext from the point of view of a detailed history of the cultural and technological production of texts, reading, writing, and theories of discourse.
