There was a lot of discussion of “digital tools” used in DH. The way I see it, there are two opposite (yet equally useful) approaches: 1) a DHer looks at the digital tools at his or her disposal and asks, “How can I integrate these into my field of research or pedagogy?” or 2) a DHer evaluates systems of research and pedagogy that may be lacking, and then finds the right digital tools with which to get the job done more effectively. In either case, I think the common thread is the DHer’s dedication to the integration of these tools for the betterment of his primary field of study.
