From Humanist, an essay on Computing or Humanities? The Growth and Development of Humanities Computing which mentions what is happening at King’s and Willard McCarty and Harold Short’s map of a Methodological Commons.
I tend to take a very different view where Humanities Computing is not an area of computing methods and tools useful to the humanities, but a discipline that brings humanities inquiry to and through computing. The radical idea I would put forward is that computing (or at least multimedia) is a new discipline of the humanities that draws on traditions of the more established disciplines.
I have argued this in other contexts like Multimedia, Is it a Discipline? and Is humanities computing an academic discipine?. At the end of the day, the movement of ideas in both directions, from and to computing will happen. It is a pity to lose sight of how the arts and humanities bring questions, ideas, theory and craft to computing.
