For over a century, historians have conceptualized and undertaken significant, long-term projects that have simultaneously advanced historical scholarship and the nation’s historical infrastructure. Although the actual work of conceptualizing, executing and managing large-scale documentary editions and database projects has sometimes gone unnoticed, historians have for decades played an instrumental role in this most fundamental act of scholarship and professional service. It is no accident that some of the nation’s leading documentary editors, for example, are also among the most accomplished and sought-after experts in their respective fields. Documentary Editions, Databases, and the Future of Digital History, the third session in this AHA-sponsored series, calls attention to the value of large-scale projects that have advanced the profession in fundamental ways, and suggests the multiple benefits that can accrue to the historians and departments that choose to adopt and sustain them. It asks: How have historical documentary editions and database projects shaped historical study and training, and how might they in future? Moderated by R. Darrell Meadows (National Historical Publications and Records Commission), this roundtable discussion brings together both historians and documentary editors engaged in long-term projects (or in one case, contemplating the adoption of a major digital project) to underscore the shared scholarly values inherent in this work, to consider the multiple positive impacts of such projects, and to spark interest among historians in conceptualizing and developing significant new projects that will help meet the scholarly needs of the historical profession in the Digital Age and for future generations of scholars. Discussants will offer brief opening remarks, to be followed by extended Q&A involving discussants, moderator, and audience alike.
