In Norrköping, Sweden, there is a building that contains what may be the largest collection of UFO-related documentation on the planet. The Archives for the Unexplained — AFU — describes itself as one of the most complete repositories for phenomenal data and UFO-related folklore anywhere in the world. It holds paper archives, book libraries, recordings, digital files, objects, and personal collections from researchers across multiple decades and dozens of countries. It is a foundation, not a government agency, but its scope exceeds most national government archives on this subject.
What AFU Holds
- Books: An extensive library of UFO and anomalous phenomena publications from around the world
- Magazines: Complete or near-complete runs of UFO periodicals from multiple countries and decades
- UFO report files: Raw investigation files from Swedish and international UAP cases
- Clippings: Newspaper and magazine clippings archive spanning decades of media coverage
- Audio and video: Recordings of witness interviews, lectures, broadcasts, and case documentation
- People and groups: Archives of individual researchers and UFO organisations — their correspondence, notes, and collections
- Pictures and objects: Physical evidence artefacts and photographic documentation
- Downloads: Partially digitised collection accessible at files.afu.se
Recent Developments
AFU remains active and growing. In November 2025, the library of Swedish folklorist Ebbe Schön was donated to AFU, adding a significant academic collection to its holdings. In February 2026, AFU published an interview article headlined “The Man Sitting on More UFO Evidence Than Anyone Alive” — describing someone with a private collection potentially exceeding even AFU’s holdings. A Swedish university incorporated AFU into a university-level UFO research course. The Yes Theory YouTube channel filmed at AFU. Clas Svahn — a co-founder of AFU — was named People’s Educator of the Year 2024 in Sweden.
The Oracle Assessment
AFU exists because governments do not preserve everything. The UK destroyed its UAP files until 1967. The US classified its records for decades. Sweden’s civilian researchers built an independent archive starting in 1973 that now serves as a global reference resource. In the era of PURSUE and GEIPAN, AFU represents the complementary private-sector preservation layer — the material that governments never collected, destroyed before they could, or chose not to archive. files.afu.se is one of the most significant UAP research portals that almost no one outside the research community knows exists.
