The digital humanities (DH) is a broad spectrum of tools and practices that bridge the humanities and computer science. By applying analytical and visualization tools to areas such as history, literature, art, and music, researchers discover new patterns and questions to ask. At the most basic level, digital humanities simply refers to the use of digital tools and methods to further scholarship. At its more complex, digital humanities involves reimagining the way we approach sources and data, research, narrative, and the publication and interpretation of scholarship.
The answer to "what is digital humanities?" will often differ depending upon whom you ask. A great example of this is Jason Heppler's What is Digital Humanities? website. Each time you refresh the page you will receive a different answer to the question. Heppler created this site based on responses from participants who attended the Day of DH between 2009 and 2014. In January of 2015, his database of responses contained 817 rows--meaning that for his site, there are 817 different answers to the question of what is digital humanities.
These resources will provide you with a more comprehensive idea of what the digital humanities are, the history of and challenges within the field, and debates about methodologies.
