We index over 250M scholarly works from 250k sources, with extra coverage of humanities, non-English languages, and the Global South.

We link these works to 90M disambiguated authors and 100k institutions, as well as enriching them with topic information, SDGs, citation counts, and much more.

Export all your search results for free. For more flexibility use our API or even download the whole dataset. It's all CC0-licensed so you can share and reuse it as you like!
