Inter-University Consortium for Political and Social Research, (University of Michigan)
ICPSR, the world's largest repository of computer-readable social science data, acquires, processes, and distributes data collections on a broad range of topics.
Students, faculty, and staff on the Yale network may download data directly from ICPSR. If the codebook for the data is available in print only and is not already in the Social Science Library collection, it will be sent to SSL. Be sure to enter your e-mail address when downloading data so that you can be notified when the print codebook arrives. To locate codebooks already in the SSL collection, search Orbis, the library’s online catalog, to get the call number.
