OpenAlex is a fully open catalog of the global research system. It's named after the ancient Library of Alexandria and made by the nonprofit OurResearch.


The OpenAlex dataset describes scholarly entities and how those entities are connected to each other. There are five types of entities:
  • 📄
    Works are papers, books, datasets, etc; they cite other works
  • 👩
    Authors are people who create works
  • 📚
    Venues are journals and repositories that host works
  • 🏫
    Institutions are universities and other orgs that are affiliated with works (via authors)
  • 💡
    Concepts tag Works with a topic
Together, these make a huge web (or more technically, heterogeneous directed graph) of hundreds of millions of entities and billions of connections between them all.
You can read more about the entity objects that make up OpenAlex, or about the data more broadly.


OpenAlex data is completely free and open, provided under a CC0 license. There are three ways to actually get the OpenAlex dataset:
