Counts reflect the records this archive has indexed from the official War.gov/UFO portal across PURSUE Releases 01–04. They count indexed records, not pages or individual files, and may differ from cumulative figures quoted in press coverage. See the Release Comparator for per-release breakdowns and the complete guide for methodology.
