We are developing a digital library to help during the long-term recovery from the mass shooting on April 16, 2007 at Virginia Tech. Content comes from uploaded texts, images, videos, and other files, as well as pages crawled from the Web, and information collected, with permission, from those working with Web 2.0 sites like Facebook and Flickr. We are applying data/text mining, social network analysis, and information visualization methods to facilitate systems science, providing key added-value services, especially to social and behavioral scientists seeking faster and easier ways to analyze, model, understand, and test hypotheses. We consider how technologies influence communications. We aim to support the university, local community, region, nation, and the world, as it seeks to learn from a tragic event.A Digital Library for Recovery, Research, and Learning from April 16, 2007 at Virginia Tech This paper is about our vision, early work, and plans to help with the recovery from the mass shooting on April 16, 2007 at Virginia Tech -to support research and learning using a digital-library-based approach. We also hope this will lead to faster and more effective methods for applying the social and behavioral sciences to address tragic events and their aftermath, much as advanced techniques have been applied to the natural sciences in e-science initiatives (Atkins et al., 2003).The backdrop of our work is the set of April 16 related experiences of the sixteen people who have contributed to this paper. We all decided to express our care through hard work, as a result of feeling a constructive sense-making impulse to collect related information, organize it, make it accessible, and preserve it for the future. In the interest of brevity, we provide just two representative comments on our personal experiences: The context of our work is a world in which radical changes have occurred as a result of the convergence of many innovations and "flattening" trends, including globalization, advanced information technologies, openness (Raymond, 1999; Van de Sompel & Lagoze, 2000), collaboration/competition/workflows, new economies, and socio-political realignments (Friedman, 2006). One response to these changes is the move, in projects like ours, to develop cyberinfrastructure (NSF, 2007). Another is to help prepare professionals, as well as the broad base of students in countries like the United States of America, for Living In the KnowlEdge Society (LIKES) (Fox, 2007a(Fox, , 2007b. In particular, for April 16, we are building a digital library (Arms, 2000;Chen & Fox, 1996;Fox, Suleman, Madalli, & Cassel, 2004;Fox, 1993;Fox, Akscyn, Furuta, & Leggett, 1995; Fox & Marchionini, 1998;Fox & Sornil, 1999Fox & Urs, 2002;Lesk, 1997Lesk, , 2005, which combines content and flexible services to support the needs of a targeted user community. Thus, we advance beyond the usual highly sequenced and preplanned approach to research and education (see Figure 1). We believe this is the right type of supp...
