Authors are people who create works.
OpenAlex indexes about 213M authors, with thousands added daily. The Canonical External ID for authors is ORCID; only a small percentage of authors have one, but the percentage is higher for more recent works.
Our information about authors comes from MAG, Crossref, PubMed, ORCID, and publisher websites. We use an algorithm to disambiguate authors; this uses an author’s name, their publication record, ther citation patterns, and (where available) their ORCID.
So for example, if J. Schmidt and John Jacob Jingleheimer Schmidt both write about 19th-century ketchup production, we’ll treat them as one author–but we won’t include the JJJ Schmidt who writes about weasel migration (even though his name is their name, too).
String: The OpenAlex ID for this author.
String: The name of the author as a single string.
display_name: "Jason Priem"

Object: All the external identifiers that we know about for this author. IDs are expressed as URIs whenever possible. Possible ID types:
wikipedia(String: this author's Wikipedia page)
Object: This author's last known institutional affiliation. In this context "last known" means that we took all the Works where this author has an institutional affiliation, sorted them by publication date, and selected the most recent one.
score(Float): The strength of association between this author and the listed concept, from 0-100.
display_name: "Computer science",
display_name: "Political science",
Any works or citations older than ten years old aren't included. Years with zero works and zero citations have been removed so you will need to add those in if you need them.
String: A URL that will get you a list of all this author's works.
We express this as an API URL (instead of just listing the works themselves) because sometimes an author's publication list is too long to reasonably fit into a single author object.
