The ISDC Data Catalog contains information on over 600 datasets covering an extensive range of key economic and social quantitative data, spanning several disciplines and themes. The bulk of the datasets described in this catalog are micro-level. Each dataset within the collection is described by bibliographic details, methodological information, abstract, geographical coverage and temporal coverage. Links to associated metadata include references to publications, subject keywords, extended metadata sources and links to related datasets, clustered in "Data Series".
The content of this catalog is structured in DDI format - an international standard for technical documentation describing social science data. The search engine is based on NESSTAR - a European software serving as an infrastructure for publishing and sharing data on the web.
