It contains metadata for 209M works (journal articles, books, etc); 2013M disambiguated authors; 124k venues (places that host works, such as journals and online repositories); 109k institutions; and 65k Wikidata concepts (linked to works via an automated hierarchical multi-tag classifier). The dataset is fully and freely available via a web-based GUI, a full data dump, and high-volume REST API. The resource is under active development and future work will improve accuracy and coverage of citation information and author/institution parsing and deduplication.","external_url":"https://arxiv.org/abs/2205.01833","cited_by_count":273,"metadata_source":"pith","metadata_fetched_at":"2026-08-05T02:28:24.338817+00:00","pith_arxiv_id":"2205.01833","created_at":"2026-05-10T00:49:48.929958+00:00","updated_at":"2026-08-05T02:28:24.338817+00:00","title_quality_ok":true,"display_title":"OpenAlex: A fully-open index of scholarly works, authors, venues, institutions, and concepts","render_title":"OpenAlex: A fully-open index of scholarly works, authors, venues, institutions, and concepts"},"hub":{"state":{"work_id":"01569e5d-750c-4621-b5ec-9bec2aa7a6b4","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":50,"external_cited_by_count":273,"distinct_field_count":14,"first_pith_cited_at":"2023-12-27T11:04:13+00:00","last_pith_cited_at":"2026-07-02T16:47:14+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-08-23T12:59:22.046058+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":3},{"context_role":"dataset","n":1}],"polarity_counts":[{"context_polarity":"background","n":3},{"context_polarity":"use_dataset","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
