Use the DiRT Directory to identify DIGITAL TOOLS
"The DiRT Directory is a registry of digital research tools for scholarly use. DiRT makes it easy for digital humanists and others conducting digital research to find and compare resources ranging from content management systems to music OCR, statistical analysis packages to mindmapping software."
The Carolina Digital Humanities Initiative has a broad list of DH tools for various types of applications such as data cleaning, wireframing, timeline tools, mapping tools and network analysis, among others.
