re3data
Verified working Jul 31, 2026
A searchable registry for finding research data repositories worldwide.
re3data is a directory of research data repositories, with thousands of indexed repositories across disciplines and countries. Users can search or browse repository records to identify places to archive, discover, or evaluate research data infrastructure.
Why it stands out
- Focuses specifically on research data repositories rather than general publications or institutional websites.
- Uses a maintained metadata schema with multiple published schema versions.
- Covers repositories globally, with browse paths by both discipline and country.
- Database entries are made openly reusable to the extent possible under a rights waiver.
Good to know
- It indexes repository records, not necessarily the datasets stored inside each repository.
- Coverage is curated and may depend on submitted or reviewed repository information, so it should not be treated as a complete global inventory.
- Repository suitability still needs to be verified on the target repository’s own site, especially for deposit rules, costs, and access policies.
Under the radar: If you cite the registry itself in a report or data-management plan, use the service DOI shown in the footer rather than only linking to the homepage.

Research data librarians and open-science support teams can find repositories to recommend for data deposit and discovery. Researchers can compare repository options before choosing where to publish a dataset. Funders and institutions can inspect repository metadata when assessing data-management plans. Data stewards can browse by subject or country to map repository coverage in a field or region.
Searchable registry of 3,500+ research data repositories; browsing by subject and country; repository suggestion workflow; published metadata schemas; news, analytics, FAQ, and governance information; citation guidance for the service.
Technical Notes
- A documented re3data API is available for programmatic access to registry metadata.
- Repository metadata is structured around published re3data schemas, including Schema 4.0 and earlier versions.
- Database entries are openly reusable to the extent possible, supporting downstream harvesting and reuse.

Open access to millions of STEM preprints before journal publication.
Open Data & Research PortalsarXiv is a long-running open archive for scholarly articles, especially preprints, across physics, mathematics, computer science, statistics, quantitative biology, quantitative finance, electrical engineering, systems science, and economics. Users can search or browse by subject area and access papers without a paywall, but arXiv itself does not peer review the material it hosts.

Open Data & Research PortalsSocArXiv is a preprint service hosted on OSF for sharing working papers and other social science research before formal journal publication. It helps researchers make manuscripts discoverable, citeable, and accessible while keeping them connected to the broader OSF research infrastructure.
