The Social Science Data Archive (SSDA) is the repository at Yale for machine-readable data sources in the social sciences. The SSDA owns and maintains a major collection of data from academic surveys, public opinion surveys, government agencies, international organizations, and related groups. SSDA codebooks and reference services are available through the Center for Science and Social Science Information. The StatLab provides technical assistance for dataset users. The SSDA holdings are restricted to use by the Yale community.
As of 2013, StatCat is no longer updated or in use. All holdings of the Social Science Data Archive and ICPSR records can be found cataloged in Orbis:
