OpenAlex is a bibliographic catalogue of scientific papers, authors and institutions accessible in open access mode, named after the Library of Alexandria. It started operating in January 2022 by OurResearch as a successor of the terminated Microsoft Academic Graph. OpenAlex competes with commercial products such as Clarivate's Web of Science or Elsevier's Scopus, and is complemented by bibliometrics tools and an API. OpenAlex is challenging Web of Science and Scopus as a free, open-source research index, and it already covers over 250 million scholarly works.
