The Harvard Project on the Soviet Social System is a collection of some 700 interview transcripts conducted with refugees from the USSR during the early years of the Cold War. A unique source for the study of Soviet society between 1917 and the mid-1940s, it boasts vast amounts of one-of-a-kind data on political, economic, social and cultural conditions. Access to the HPSSS Online resource is unrestricted. A guide to using the project has also been posted on the site that details the methodological limitations and possibilities of this online resource at some length: http://hcl.harvard.edu/collections/hpsss/working_with_hpsss.pdf
HPSSS Online is a web resource that makes the Harvard Project on the Soviet Social System accessible to researchers and students worldwide for the first time.
