CESSDA provides large scale, integrated and sustainable data services to the social sciences, having evolved from a network of European data service providers into a legal entity and large-scale infrastructure under the auspices of the European Strategy Forum on Research Infrastructures (ESFRI) Roadmap in June 2013.
The CESSDA website compiles links to the data services/archives of member and affiliate countries.
May 2017: "At CESSDA, we are working on building a new and improved Products and Services Catalogue, as part of a wide-ranging plan to establish a common infrastructure for CESSDA members. It is due to go into service in late 2017/early 2018. In the meantime, we would kindly like to ask researchers to go directly to the data sources hosted by the Service Providers listed below and search for data there."
