UFO Library
100 essential books — foundational, skeptical, abduction, and military UAP shelves.
The Flying Saucers Are Real
A retired Marine Corps major and aviation writer built the first influential public case that flying saucers were interplanetary craft, drawing on the Kenneth Arnold sighting, the Mantell crash, and the Chiles-Whitted encounter. Keyhoe argued the Air Force knew more than it admitted and was managing public disclosure to avoid panic.
The Interrupted Journey: Two Lost Hours Aboard a Flying Saucer
Fuller's account of Betty and Barney Hill's 1961 New Hampshire sighting and their subsequent hypnotic-regression sessions with psychiatrist Benjamin Simon was the first book-length treatment of a UFO abduction narrative, complete with transcripts and the Hills' star-map and entity drawings.
Missing Time: A Documented Study of UFO Abductions
A New York artist turned investigator was the first to systematically look for patterns across many abductee accounts, using hypnotic regression to recover 'lost' periods of time that witnesses could not otherwise explain. The book established missing time itself as a diagnostic red flag for a possible abduction.
Intruders: The Incredible Visitations at Copley Woods
Hopkins built out the abduction thesis around 'Kathie Davis' of Indianapolis, presenting a years-long pattern of encounters that he interpreted as evidence of an alien breeding program harvesting human reproductive material to create hybrid offspring. It spent four weeks on the New York Times bestseller list and was adapted into a 1992 CBS miniseries.
Secret Life: Firsthand, Documented Accounts of UFO Abductions
Drawing on interviews with sixty abductees and hypnotic regression of over 300 accounts, historian David Jacobs assembled a minute-by-minute composite of a 'typical' abduction, arguing for a systematic alien breeding program creating human-alien hybrids for an undisclosed purpose. It remains the most granular procedural account of the alleged abduction experience.
Abduction: Human Encounters with Aliens
A Pulitzer Prize-winning Harvard psychiatrist presented thirteen detailed case studies of self-described abductees, arguing their experiences — while not necessarily literal spacecraft visitations — pointed to something ontologically real that Western materialism was unequipped to explain. Mack's Harvard affiliation triggered a formal (ultimately unsuccessful) faculty inquiry into his methods.
Communion: A True Story
Horror novelist Strieber recounted his own December 1985 encounter at an upstate New York cabin — waking paralyzed to a small dark figure in his room — and the hypnotherapy sessions (conducted with Budd Hopkins) that surfaced further memories. Its stark cover painting of a wide-eyed Grey face became the single most recognizable image in UFO culture.
The Roswell Incident
The book that resurrected the 1947 Roswell story after three decades of obscurity, arguing an extraterrestrial craft crashed after being struck by lightning while observing nearby nuclear weapons activity, and that the U.S. military staged a cover story and cover-up within hours.
Fire in the Sky: The Walton Experience
Walton's first-person account of his November 1975 disappearance during an Arizona logging job — a claimed five-day abduction that triggered a massive search and briefly made him a homicide suspect — remains one of the best-documented alleged abduction cases, with all six of his coworkers passing polygraph tests on the sighting itself.
Imminent: Inside the Pentagon's Hunt for UFOs
The former head of the Pentagon's Advanced Aerospace Threat Identification Program recounts his years investigating UAP encounters at military sites, his resignation in protest of internal secrecy, and his role in triggering the 2017 New York Times exposé — while alleging the government holds retrieved non-human technology and biological material.
Incident at Exeter
Fuller personally investigated a wave of radar-visual and pilot-witnessed sightings around Exeter, New Hampshire in fall 1965, interviewing dozens of witnesses including police officers, and claimed to see a UFO himself during the reporting. It is one of the best-documented small-town flaps of the pre-abduction era.
The Mothman Prophecies
Keel's year embedded in Point Pleasant, West Virginia (1966-67) documenting a winged, red-eyed entity, Men in Black visitors, and a cascade of high-strangeness events that he links to the collapse of the Silver Bridge in December 1967. Keel argued the phenomenon manipulates human perception rather than behaving like a physical craft.
Crash at Corona: The U.S. Military Retrieval and Cover-Up of a UFO
Nuclear physicist Friedman, the original civilian Roswell investigator, and aviation writer Berliner drew on interviews with over 100 witnesses to argue for two New Mexico crash sites and a coordinated multi-decade government cover-up, going further than Berlitz and Moore's original account.
You Can't Tell the People: The Definitive Account of the Rendlesham Forest UFO Mystery
Bruni gained access to police, Ministry of Defence, and U.S. military sources to reconstruct the December 1980 Rendlesham Forest incident, in which USAF security patrolmen at RAF Woodbridge/Bentwaters reported a landed craft and physical traces in the forest between the twin bases.
UFOs and the National Security State: Chronology of a Cover-Up, 1941-1973
Historian Dolan built a chronological narrative of nearly 300 documented U.S. military UFO encounters using declassified records, tracing the Robertson Panel, the Condon Committee, and over 50 Air Force, Navy, and Army bases with UFO-related activity to argue the security state took the phenomenon far more seriously in private than in public.
Skinwalkers at the Pentagon: An Insiders' Account of the Secret Government UFO Program
Written by the program manager and lead scientists of the Pentagon's AAWSAP/AATIP effort and cleared for public release by the Department of Defense, the book documents how a government UAP research program investigating the Nimitz encounters expanded to include paranormal phenomena reported at Skinwalker Ranch.
Flying Saucers Have Landed
Adamski's claimed November 1952 California desert meeting with 'Orthon,' a benevolent human-looking Venusian, founded the entire contactee movement, paired in this joint volume with Leslie's more scholarly survey of historical aerial anomalies. Adamski's supporting photographs were later shown to depict small models built from ordinary hardware.
Night Siege: The Hudson Valley UFO Sightings
Hynek's final research project, completed by Imbrogno and Pratt after his 1986 death, documented over 7,000 reports of a large boomerang-shaped craft over New York's Hudson Valley and Connecticut between 1982 and 1995, presenting witness data without asserting a firm explanation.
The Cash-Landrum UFO Incident
MUFON's longtime international director spent over a decade investigating the December 1980 Texas case in which Betty Cash, Vickie Landrum, and Colby Landrum suffered radiation-like burns and lasting illness after encountering a diamond-shaped object escorted by military helicopters, documenting the medical evidence and the pair's unsuccessful lawsuit against the U.S. government.
UFOs: Operation Trojan Horse
Keel's earlier and more theoretical work argued that UFOs and their occupants are not extraterrestrial visitors but a persistent 'ultraterrestrial' phenomenon that has manipulated human belief for millennia, adapting its costume — angels, fairies, demons, spacemen — to match each era's expectations.
Passport to the Cosmos: Human Transformation and Alien Encounters
Mack's follow-up moved beyond cataloguing abduction accounts to argue the experiences function as a spiritually transformative ontological shock, reframing entity encounters as a kind of forced initiation that challenges the boundary between self and cosmos rather than a simple biological experiment.
The Andreasson Affair
MUFON investigator Fowler documented Betty Andreasson's 1967 South Ashburnham, Massachusetts encounter through extensive hypnotic regression, uncovering an elaborate narrative of alien contact, telepathic communication, and mantis-like beings that became a template for later abduction case studies.
UFO Crash at Roswell
A CUFOS-sponsored investigative team's first book-length account of their 1988-91 Roswell witness search, expanding the roster of claimed witnesses to the debris field and adding new testimony about military secrecy in the days after the crash.
The Truth About the UFO Crash at Roswell
The sequel expanded the Roswell witness list still further, incorporating mortician Glenn Dennis's controversial secret-autopsy and alien-nurse claims that later collapsed under scrutiny — a cautionary tale later cited by critics of the crash-retrieval literature's expanding witness rosters.
UFOs & Nukes: Extraordinary Encounters at Nuclear Weapons Sites
Drawing on interviews with more than 170 U.S. Air Force veterans over five decades, Hastings documents recurring reports of UFOs appearing over ICBM silos coinciding with unexplained missile malfunctions, including a March 1967 Montana incident in which numerous missiles reportedly went off alert moments after a disc-shaped object was seen nearby.
The Phoenix Lights: A Skeptic's Discovery That We Are Not Alone
A physician who personally witnessed and photographed the March 13, 1997 mass sighting recounts her journey from skepticism to conviction, compiling eyewitness testimony from police dispatchers, pilots, and then-Governor Fife Symington, who publicly reversed his earlier mockery of the event.
Above Top Secret: The Worldwide UFO Cover-Up
British researcher Good compiled classified-document leaks, military testimony, and international sighting reports from dozens of countries to argue for a coordinated worldwide government cover-up, and was among the first to publicize the contested 'Majestic 12' documents.
UFOs and the National Security State: The Cover-Up Exposed, 1973-1991
The second volume carries Dolan's chronology through the Carter administration's UFO interest, the 1980 Rendlesham Forest incident, and the Cold War's final decade, arguing the security apparatus's posture hardened into a more sophisticated, better-funded secrecy regime after the Condon Report's public 'closing of the door.'
In Plain Sight: An Investigation into UFOs and Impossible Science
Australian investigative journalist Coulthart interviewed senior U.S. military, intelligence, and congressional sources in the wake of the 2017 Navy video disclosures, arguing the evidence for genuinely anomalous craft — and for a compartmented government retrieval program — was stronger than most mainstream reporting acknowledged.
Flying Saucers — Serious Business
A veteran broadcast journalist compiled hundreds of sighting cases into a bestselling popular argument that the government was concealing what it knew about UFOs, reaching a much wider lay audience than the more technical Keyhoe and Ruppelt books.
They Knew Too Much About Flying Saucers
Barker turned Albert Bender's abrupt 1953 shutdown of the International Flying Saucer Bureau into the founding legend of the sinister, silencing Men in Black, blending real events with what Barker later admitted was substantial embellishment for entertainment value.
Flying Saucer Occupants
The founders of APRO (the Aerial Phenomena Research Organization, one of the first serious civilian UFO investigation groups) compiled and analyzed the first systematic international catalogue of occupant/entity sightings, years before the abduction era standardized the Grey.
The UFO Evidence
Compiled by the National Investigations Committee on Aerial Phenomena, this was the first attempt to present UFO sightings as an organized evidentiary case file — hundreds of reports with witness backgrounds, radar corroboration, and physical trace data — aimed squarely at Congress and the scientific establishment.
Witnessed: The True Story of the Brooklyn Bridge UFO Abductions
Hopkins' most controversial case file centers on 'Linda Napolitano,' who claimed to have been floated out of her twelfth-floor Manhattan apartment window in November 1989 in front of alleged witnesses, including UN security personnel. The claimed corroborating witnesses were never independently verified and critics called parts of the account fabricated.
The Threat: Revealing the Secret Alien Agenda
Jacobs' darker sequel to Secret Life argued the hybridization program was approaching a covert 'integration' phase in which alien-human hybrids would move undetected among the general population, a claim that alarmed even some abduction researchers as speculative overreach.
Transformation: The Breakthrough
Strieber's sequel to Communion continued documenting his encounters and reframed them as part of a deliberate transformative process rather than a hostile abduction, moving his narrative further toward a spiritual and consciousness-focused interpretation of the visitor phenomenon.
The Allagash Abductions
Fowler investigated the claimed 1976 multiple-witness abduction of four friends canoeing in Maine's Allagash wilderness, using hypnosis to recover matching accounts from all four men — a case frequently cited by believers as unusually strong because of its multiple independent witnesses.
Into the Fringe: A True Story of Alien Abduction
A literature professor turned researcher documented her own family's alleged abduction experiences and grew increasingly critical of mainstream abduction researchers, arguing the phenomenon was far darker, more deceptive, and more invasive than Hopkins- or Jacobs-style accounts suggested.
Left at East Gate: A First-Hand Account of the Rendlesham Forest UFO Incident
Written by one of the USAF airmen present at Rendlesham Forest, this first-person account describes multiple nights of encounters, an alleged military briefing about the events, and what the authors present as a subsequent campaign of intimidation against witnesses.
Firestorm: Dr. James E. McDonald's Fight for UFO Science
A biography of the atmospheric physicist James McDonald, who used his scientific standing to publicly challenge the Air Force's dismissive UFO stance in the late 1960s — a campaign that made him ufology's most credentialed scientific advocate before his death by suicide in 1971 amid professional and personal turmoil.
Sekret Machines: Chasing Shadows
Musician-turned-UAP-researcher DeLonge and esoteric historian Levenda opened a planned nonfiction/fiction hybrid series exploring UFO history and alleged government retrieval programs — the project that helped fund and publicize DeLonge's To The Stars Academy, which later played a role in surfacing Navy UAP videos.
Alien Agenda: Investigating the Extraterrestrial Presence Among Us
Investigative journalist Marrs synthesized decades of crash-retrieval, abduction, and cover-up claims into a single sweeping narrative aimed at a mass-market audience, becoming a bestseller that introduced many general readers to the wider UFO conspiracy literature.
Behind the Flying Saucers
A Variety magazine columnist reported claims from two con men (posing as scientists) of multiple captured saucers and dead alien crews in the New Mexico desert. The sources were exposed as a swindle in a 1952 True magazine investigation, but the book had already sold widely and pioneered the crash-retrieval narrative template Roswell literature would later inherit.
The Day After Roswell
A retired Army colonel and former Eisenhower National Security Council staffer claimed personal stewardship of recovered Roswell debris and credited it with seeding Army reverse-engineering that produced integrated circuits, fiber optics, and Kevlar. A New York Times bestseller, it drew heavy criticism for documented factual and chronological errors.
Top Secret/Majic
Nuclear physicist Friedman mounted a detailed defense of the authenticity of the contested 'Majestic 12' documents, which purport to show a 1947 Truman-authorized committee overseeing recovered saucer wreckage, arguing document experts who dismissed them as forgeries had been too hasty.
Need to Know: UFOs, the Military and Intelligence
Good's later synthesis compiled newly surfaced military and intelligence testimony from multiple countries gathered in the years since Above Top Secret, updating his cover-up thesis with post-Cold-War declassifications and additional international witness accounts.
Sight Unseen: Science, UFO Invisibility, and Transgenic Beings
Hopkins and documentary filmmaker Rainey argued the abduction phenomenon involves genuine physical technology capable of rendering craft and beings invisible or unnoticed by non-abductees, presenting alleged physical evidence including unusual scarring and unexplained pregnancies as support for a literal hybridization program.
