The Data Preservation Alliance for the Social Sciences (Data-PASS) is a partnership of social science data archives devoted to identifying, acquiring and preserving primary source data at-risk of being lost to researchers. Examples of at-risk data include opinion polls, voting records, large-scale surveys on family growth and income, and many other social science studies. This will be added to Data Mining Resources Subject Tracer™. This has been added to Research Resources Subject Tracer™ Information Blog.
