Digital Humanities is interdisciplinary in nature. As such, it is difficult to point to one or two databases as the place to search for relevant articles. Where you look may depend on a particular disciplinary interest - e.g. literature, music, history - or you may need articles related to a particular topic or method of analysis - e.g. GIS mapping, topic modelling, software studies, text mining, etc.
Below are a few suggested databases where you might start your digital humanities research. For help with more specific questions, contact Sherri or use UVA's Ask a Librarian options.
