So, if the digital humanities is, neither in fact nor in principle, a discipline, then what is it? Surely, with its growing army of followers and plethora of concrete institutional manifestations, it must have some basis in a reality other than its own existence. In fact it does. The digital humanities, as both a broad collection of practices and an intense, on-going interpretive praxis generative of such practices, is best thought of as having two very concrete but equally elusive dimensions. One the one had, the digital humanities (conceived of in the plural) comprises something very much like a curriculum, an inter-related collection of subject domains and resources that, as a whole, contributes to both the construction of knowledge and the education of people. Although no one individual can master an entire curriculum, a curriculum nevertheless has a logic, a coherence, and even a center of gravity.
