Here's an excerpt:
As an emerging field, DH has, thus far, had a broad characterization. As technology and our understanding of it change, so do the limits of DH. There has been some debate as to whether DH constitutes a discipline of its own or is simply an application of new technologies to existing disciplines. In either case, DH can be understood as the place where traditional humanities research methodologies and media/digital technologies intersect. DH is more than the digitization of existing processes, documents, and artifacts. It is often data-driven, answering humanities research problems with multidisciplinary, interdisciplinary, and cross-disciplinary approaches within the digital/IT realm. The current challenge for DH lies in establishing itself in traditional academic environments. . . .
There are many useful resources available online, including general sites as well as e-publications, tools, tutorials, and organizations. We have tried to include a representative sample of those we feel are most important or could be most useful for librarians getting started in the digital humanities.
