How much time do you have?
Quick orientation
Browse the Timeline from 1947 forward. It covers eight decades of encounters, government programmes, and disclosure in chronological order. Each entry links to sources.
Deep dive into a case
Pick a case from the Case Files. Each one pulls together sighting reports, named witnesses, newsletter coverage, and government programme references. Start with the Roswell Incident or the USS Nimitz encounter. For primary government documents, browse the Blue Book Microfilm Viewer: 3,464 digitised frames from NARA's Project Blue Book microfilm collection.
Read the primary sources
Search across 68,000+ newsletter articles from 614 civilian research publications. These are the original field reports, editorials, and analyses written by the people who investigated these cases firsthand.
Who are you?
Curious but unfamiliar
Start with the Timeline. Events from the 1940s through 1960s provide essential context for what is happening in Congress today. Then try the Encyclopedia when you hit a term or programme you do not recognise.
Covering the story
The Case Files give you sourced dossiers on individual incidents. The Encyclopedia maps who was involved, their organisations, and connected cases. The Article Search lets you trace how a story was reported across publications over decades.
Academic or independent
The Country pages chart sighting activity decade by decade with the source records attached. The Historic Newsletters archive indexes hundreds of periodical titles spanning 1937 to 2026. Cross-references between cases, people, and primary sources are linked in-line on every page.
