There are both subject-specific and generic data repositories. In addition, data portals enable you to search for research data across several repositories.

Subject-specific data repositories

• SowiDataNet|datorium – research data repository for social sciences and economics.
• OpenICPSR – share and find social, behavioural and health-scientific research data.

Further subject-specific data repositories or disciplinary data centres can be found below:

• Re3Data is a searchable directory of all the main research data repositories in all scientific disciplines.
• Repository Finder helps to identify research data repositories that support the principles of FAIR data.
• RIsources enables German repositories to be found.
• Fairsharing.org can be used as a reference guide, to identify databases or repositories, among other things.
