Overview

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.

Data

The OpenAlex dataset describes scholarly entities and how those entities are connected to each other. Types of entities include works, authors, sources, institutions, concepts, and publishers.
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.
