The main theme for my comprehensive exam could be labelled as the (im)mediacy of writing ranging from the idea of language and thus writing as directly expressing thoughts to the alleged discrepancy between embodied handwriting and various forms of disembodied typewriting.
I have now organized the books around three areas:

1. the (gendered) body and technology
   bodies and their interrelations with technologies, acknowledging their fundamental involvement with and significance to each other
2. corporeality and its communication through media and society
   how we come to interact the way we do: media technologies, social and physical forms of interactions, their roots and trajectories over time; this also includes, as an important focus, literature on ‘education’ in a broad sense (training of the body and mind - Elias, Foucault, Mauss, Lakoff/Johnson) as well as in a more narrow sense (training of the hand - Goldberg, Kittler, Thornton).
3. the mediality of (hand)writing
   handwriting in the context of other historical and technical practices and forms of writing; or – in a different terminology – the pre-/re-/mediation of writing

I should probably use the term intermediality for that last section, but it seems like such a pleonasm. Waiting to hear back from my supervisor and second reader with comments.
