da|ra is a registration service for research data from the social and economic sciences. The registration agency is operated by GESIS - Leibniz Institute for the Social Sciences and the ZBW - Leibniz Information Centre for Economics. The registration agency aims to be an integrated contact point for data providers and secondary users of social and economic research data. On the one hand, it offers researchers the service of long-term data storage, archiving and easy retrieval. On the other hand, it helps to find data on a research topic or a publication.
