The poster will showcase diverse added-value services provided by the GESIS RDC International Survey Programs as a central access point for cross-national and cross-cultural survey databases with a wide thematic scope of attitudinal data and subjective social indicators, encompassing an ever-expanding number of countries across several decades. The RDC International Survey Programs was established in order to focus the institution's expertise and activities in this field, benefiting from prominent involvement in almost all steps of the research data life cycle: from the standard demography development for the ISSP or the multilingual instrument documentation and development in the EVS, over data harmonization and detailed documentation in close cooperation with the principal investigators (CSES, EVS, ISSP) to online access facilities to individual level datasets and related materials, even across distributed platforms where necessary (European Elections Study). To complement the infrastructure components, the analysis potential of the comparative database will be exemplified in research oriented data reports and workshops. The poster will also point to future potentials such as the strengthening of links between comparative survey programs and other data types for multi-level analysis.
