Authors Overview

Schema reference for Authors entities

Authors are people who create works. OpenAlex indexes tens of millions of disambiguated author profiles.

Filter, sort, and group_by fields

The API supports filtering, sorting, and grouping on authors fields. See Filtering, Sorting, and Grouping for syntax.

Fields marked (deprecated) are .search filters — use the search parameter instead.
