PURSUE UAP Documents Dataset: A structured catalog of declassified U.S. government UAP records (2026)

A structured catalog of every U.S. government UAP record released under the PURSUE initiative (Presidential Unsealing and Reporting System for UAP Encounters), covering all public tranches from May 8, 2026 onward: 351 records, 1947–2026, 12 source agencies, 7 releases. This is a finding aid, not a document dump. Each row identifies one released record and states its releasing agency, the document/event year, the release tranche, the file-package composition, the location as named in the record, the official source URL, and — the part that does not exist in any other public index of these files — a set of source-status labels describing what kind of evidence the record is. Source-status labels are applied in two layers. Layer 1 is derived mechanically from record metadata and covers all 351 records: official-source (351), public-rendition (116), historical-archival (150), witness-testimony (85). Layer 2 is editorial and applied only where a record has been researched in depth and the basis can be stated in writing: official-analysis, partial-explanation, unresolved, context-gap — 17 label applications across 11 records. Labels are verifiable statements about a record's sourcing; they are not quality ratings and not judgments about what the underlying events were. Composition by release: Release 01 (2026-05-08, 31 records), Release 02 (2026-05-22, 64), Release 03 (2026-06-12, 72), Release 04 (2026-07-10, 40), Release 05 (2026-08-07, 41), Release 06 (2026-09-18, 75), Release 07 (2026-10-23, 28). By agency: Department of War (220), FBI (52), NASA (29), CIA (23), Department of Energy (5), Department of State (4), Local Law Enforcement (8), Executive Office of the President (2), U.S. Government interagency (1), ODNI (1), ICA (1), other (5). By file type: PDF (182), video (116), image (45), audio (8). Fields: slug, title, agency, year, release, location, file_types, evidence_labels, record_url. Known limitations — including that location is free text as released rather than geocoded, that year is the document/event year rather than the release year, and that editorial-label coverage is intentionally incomplete — are documented in full in the accompanying README. The canonical, always-current version is regenerated on every build of the source archive at https://ufo-declassified.com/dataset/uap-documents.csv. The underlying documents are public-domain works of the U.S. government, hosted at war.gov/ufo. This dataset is the independent index built on top of them, and is not affiliated with any U.S. government agency.
