OpenAlex is not doing this alone! Rather, we're aggregating and standardizing data from a whole bunch of other great projects, like a river fed by many tributaries. Our two most important data sources are MAG and Crossref. Other key sources include:
- ORCID
- ROR
- DOAJ
- Unpaywall
- Pubmed
- Pubmed Central
- The ISSN International Centre
- The General Index
- Web crawls
- Subject-area and institutional repositories from arXiv to Zenodo and everywhere in between
