Different official UAP sources serve different research purposes. The fastest path is to use the right source for the right job instead of treating them as one database.
Effective UAP archive research requires understanding that the four main official sources serve fundamentally different purposes. NARA RG 615 is a document repository — it holds records transferred by other agencies and provides long-term archival custody. AARO is an active investigative office — it receives current reports, analyzes ongoing cases, and publishes case-resolution determinations. NASA is a scientific authority — it sets methodological standards and contributes analytical frameworks. The FBI Vault is a historical collection covering the 1947–1954 era of Bureau engagement and is not updated.
Matching the right source to your research question is the single most important efficiency gain in UAP archive work. If you're researching a specific post-2020 incident, start with AARO. For historical document context, start with NARA. To understand what quality of evidence exists for a given case, read NASA's methodology materials first. For 1940s–1950s research, the FBI Vault provides unique primary source material unavailable elsewhere.

A productive UAP archive session follows a specific sequence. Start with the Now Declassified incident index to identify whether a case has been formally indexed against official sources — this saves the time of independently cross-referencing multiple agency sites. For indexed cases, the incident page provides direct links to the primary source documents, AARO case references, and any associated NARA catalog entries. For cases not in the index, the NARA UAP topic guide and the AARO records page are the two most comprehensive starting points.
When you reach a NARA catalog entry, note the record group, series, and box number — these are the coordinates of the physical document. For digitized records, download the PDF directly. For undigitized records, submit a duplication request through the NARA website. AARO records are usually available immediately on the AARO site without any request process.
The most revealing UAP research happens at the intersection of multiple source types. The USS Nimitz case, for example, appears across AARO's imagery page (the FLIR1 video), the NARA RG 615 catalog (the Princeton radar log and DIA assessment), and congressional testimony transcripts from the 2023 House hearing. No single source gives the complete picture; the administrative record at NARA, the official imagery at AARO, and the sworn testimony in the congressional record each add a different dimension.
Now Declassified's incident detail pages are designed to surface these cross-source connections. Each incident links to its primary agency source, notes any AARO case-resolution status, and cross-references related incidents in the archive. The Match My Sighting tool goes further — it maps reported sighting characteristics against the full index corpus to find the closest historical parallel, giving researchers a data-backed reference point for understanding their own experiences.
