DANS-EASY is an online archiving system for depositing and reusing research data. As well as ample new datasets and collections, the collections of the former Netherlands Historical Data Archive (NHDA) and the Steinmetz Archives are also accommodated by EASY. EASY contains datasets from the humanities, health sciences, social and behavioural sciences, oral history and spatial sciences. In addition, EASY offers access to the secure micro data of Statistics Netherlands (CBS). Through EASY, data from research can be shared with others. Together we ensure sustained access and reusability of research data.
