OpenAIRE

Europe’s open-science graph — research linked to the funding behind it.

At a Glance

PublisherOpenAIRE (a European non-profit consortium, EU-funded)
Coveragethe OpenAIRE Graph aggregates, deduplicates, and enriches metadata from 2,000+ data sources — publications, research data, and software — with links to projects, funders, and citations
Accessfree and open; API and full data dumps

Our Take

OpenAIRE is the connective tissue of European open science: it doesn’t just index outputs, it links them to the grants and funders that produced them, which is exactly what you need to check compliance with open-access mandates or to trace a funder’s research footprint. For anyone working under Plan S or Horizon Europe, it’s the tool that answers “is this openly available, and who funded it?” — and before assuming a paper is paywalled, OpenAIRE (or OpenAIRE Explore) will often surface an open version. It’s metadata and linkage rather than full text, and its funder coverage is strongest in Europe. Use it for open-access discovery and funding-linked analysis.

Power Tips

  • Check OpenAIRE before assuming a paywall is final — it frequently surfaces an open version or repository copy the publisher page doesn’t show (Issue 1)
  • use the funder and project links to audit open-access compliance or map a funder’s outputs; pull the graph via API for large-scale analysis.
