ICPSR (Inter-University Consortium for Political and Social Research)
The ICPSR is one of the largest collections of quantitative data in the world. The archives contents cover a very wide range of topics, with household surveys, health conditions and health care, and public opinion being particularly strong points in the collection. Emory's local ICPSR representatives are Ms. Jennifer Doty and Dr. Robert O'Reilly. The ICPSR is also available via Databases at Emory. Please see this notice from the ICPSR on how to access the archive and its data when off-campus.
Council of European Social Science Data Archives (CESSDA)
CESSDA is a consortium of national data archives from various European countries. CESSDA's data catalogue offers a central point of access to the holdings of the individual archives. Please note that different archives will have different access policies and different practices for documentation and dissemination of data files to researchers from non-European countries. The UK Data Archive and GESIS (Leibniz-Institute for the Social Sciences) are both generally willing to allow non-European researchers access to datasets upon registration.
