Here’s a brief description of the project from the report’s Executive Summary:
In 2011-2012, Ithaka S+R examined the changing research methods and practices of academic historians in the United States, with the objective of identifying services to better support them. Based on interviews with dozens of historians, librarians, archivists, and other support services providers, this project has found that the underlying research methods of many historians remain fairly recognizable even with the introduction of new tools and technologies, but the day to day research practices of all historians have changed fundamentally. Ithaka S+R researchers identified numerous opportunities for improved support and training, which are presented as recommendations to information services organizations including libraries and archives, history departments, scholarly societies, and funding agencies.
