History
Archives for the Unexplained was founded in Södertälje in 1973 by Håkan Blomqvist, Kjell Jonsson, and Anders Liljegren, originally being called the Work Group for Ufology. The purpose was to provide information for UFO researchers and build a specialized research library for UFO literature.

In 1980, AFU was converted to a charitable foundation and the archive was moved to its current location in Norrköping. Through a special agreement in 1986, AFU is connected to the national organization UFO-Sweden, and takes the role of managing the organization's archives and libraries. The daily operation is run by a permanent staff and entirely on a voluntary basis by contributions from private sponsors. Chairman is Clas Svahn.

In 2013, its name was changed to Archives for the Unexplained.

Collection
AFU stores UFO reports submitted and documented by private and military investigators in Sweden. The archive manages UFO-Sweden's report archive. Material is continuously being added material from the organization's central and field investigators. The report archive includes about 20,000 Swedish observations and copies of all available open UFO investigations since 1946 made by the Swedish Armed Forces (about 2,000 cases, mostly ghost rockets spökraketer). The archive has received donations of comprehensive report archives from Norway, Denmark, and others.

Journals from around the world that are within the scope of the archive topics are saved regularly. The archives currently have tens of thousands of booklets. The collection includes all kinds of regularly published writings from religious cults newsletters to comics with scientific ambitions. Most of the journals describe reported UFO cases and debate of UFO topics in different parts of the world.

To organize the collection, librarians developed a specialized subject classification scheme for the topic.

U.S. News & World Report described it as "among the most comprehensive digital libraries for UFO sightings and investigations into them by governments worldwide."
