The Data Preservation Alliance for the Social Sciences (Data-PASS) is a broad-based partnership devoted to identifying, acquiring and preserving data at-risk of being lost to the social science research community. The partners coordinate identification, acquisition, and cataloging of data at risk; develop best practices for data archiving; and create a shared infrastructure and practices for cataloging and preservation. Data-PASS is led by the Inter-university Consortium for Political and Social Research (ICPSR) at the University of Michigan, the Roper Center for Public Opinion Research at the University of Connecticut, the Howard W. Odum Institute at the University of North Carolina-Chapel Hill, the Henry A. Murray Research Archive, a member of the Institute for Quantitative Social Science at Harvard University, the National Archives and Records Administration, and the Harvard-MIT Data Center.
