GESIS-ZA Central Archive for Empirical Social Research
The department GESIS-ZA archives primary material (data, questionnaires, code plans) and
results of empirical studies in order to prepare them for secondary analyses
and to make them available to the interested public. The range of the GESIS-ZA
encompasses all technical areas in which procedures of empirical and
historical social research are used. There is a close co-operation with the
University of Cologne.
