What is OpenAlex?
OpenAlex is a free, open catalogue of the world's scholarly works, authors, institutions and venues, run by the non-profit OurResearch.
OpenAlex is a free and fully open catalogue of the global research literature — works, authors, institutions, venues and concepts — built and maintained by the non-profit OurResearch. It indexes hundreds of millions of works and offers an open API and open data, as a successor to the discontinued Microsoft Academic Graph.
It matters because it is an open alternative to proprietary databases like Scopus and Web of Science: anyone can use it, and it underpins discovery and citation analysis without a paywall or licence restriction.
OpenAlex and your CV
For an academic CV, OpenAlex is a broad, open source of your publications and their citation data, linked to you by your OpenAlex author identifier.
How SigmaCV uses OpenAlex
SigmaCV resolves your OpenAlex author ID from your ORCID iD, imports your works, and — only if you opt in — derives field-normalized metrics from OpenAlex data, default off and DORA-aligned.
