Digital history is a branch of digital humanities that involves the use of digital media to facilitate historical analysis, presentation, and research. It examines and represents the past with the help of new communication technologies such as computers, the Internet, and software systems. Digital history harnesses essential features of the digital technology such as databases, hypertextualization, and networks, to create and share historical knowledge. Integration of digital history with the traditional historical methods helps to create models and maps of data extracted to create a visualization of the data. It employs different tools to extract and analyze large amounts of data that would not be manageable otherwise. This data can be placed alongside existing historiography to increase combined historical knowledge. In this book, the concept, use and applications of digital history have been described. It is appropriate for historians, researchers and students seeking detailed information in this area of digital humanities.
