+As of today, the OpenAIRE Research Graph aggregates around 450Mi metadata records with links collecting from 10K data sources trusted by scientists, including:

+* Open Access journals registered in DOAJ
+* Crossref
+* Unpaywall
+* ORCID
+* Microsoft Academic Graph
+* Datacite
+
+And repositories registered in OpenDOAR, re3data.org, FAIRSharing.org, and the EOSC Service Catalogue. Among these, prominent repositories such as:

+* UKPubMed
+* ArXiv
+* HAL
+* Zenodo
+* Figshare
+* Dryad
+* Repec

 After cleaning, deduplication, enrichment and full-text mining processes, the graph is analysed to produce statistics for the [OpenAIRE MONITOR](https://monitor.openaire.eu), the [Open Science Observatory](https://osobservatory.openaire.eu), made discoverable via the [OpenAIRE EXPLORE](https://explore.openaire.eu) and programmatically accessible via [OpenAIRE Public APIs](https://develop.openaire.eu).
 Last but not least, the Graph data are openly available and can be used by third-parties to create added value services.
