The availability of digitised sources opens new possibilities for the digital humanities. The improved accessibility of source material can facilitate social history research, particularly when combined with new research questions and perspectives. This is particularly true of research on Indian history, as historians often have to grapple with the problem of the absence of or, when available, poorly preserved sources. Thus, parallel to research, the IBO from its early days has responded to the need to create open access digital source and bibliographic repositories. Collecting and storing source material and creating digitised indexes and guides as a resource to enable research forms an important part of the IBO’s work. The IBO has two repositories that are available to scholars, upon request, free of cost. The IBO also supports collaborative repositories.
