New to UFOs and first contact? Start with Leslie Kean’s UFOs: Generals, Pilots, and Government Officials Go on the Record for firsthand accounts, then Garrett Graff’s UFO for the full government history. After that, this guide sorts the best-known books into investigators, “high strangeness” thinkers, scientists and skeptics, with a short, honest note on each and a reading path at the end. Every title, author and year below was checked against publisher, library or bookstore listings.
A quick word on the evidence
Officials now usually say UAP (unidentified anomalous phenomena) rather than UFO. In December 2017 the New York Times reported that the Pentagon had quietly funded a UFO study program, which brought the subject back into the mainstream. In March 2024 the Pentagon’s All-domain Anomaly Resolution Office (AARO) released a historical review that found no evidence that any UAP sighting represented extraterrestrial technology. Many of the authors below disagree with that conclusion. Reading both sides is the best way in.
Start here
UFOs: Generals, Pilots, and Government Officials Go on the Record by Leslie Kean (2010)
Investigative journalist Leslie Kean collects firsthand accounts from military pilots, generals and government officials in several countries, alongside her own reporting on how governments have handled the subject. It’s sober in tone and avoids claims about who or what is behind the sightings. Kean later co-wrote the 2017 New York Times story on the Pentagon program, so this is a natural first book.
UFO: The Inside Story of the US Government’s Search for Alien Life Here—and Out There by Garrett M. Graff (2023)
Historian and journalist Garrett Graff traces U.S. military, intelligence and scientific efforts to study UFOs from 1947 to the modern UAP era, and sets them beside the scientific search for life elsewhere. Reviewers found it accessible and well researched, though some critics wanted more skepticism. It’s the best single overview for beginners who want the whole timeline.
Investigators and insiders
The UFO Experience: A Scientific Inquiry by J. Allen Hynek (1972)
Astronomer J. Allen Hynek spent years as a scientific consultant to the U.S. Air Force’s UFO investigations. In this book he set out the “close encounters” categories (first, second and third kind) that are still used today. It’s dated in places but essential for understanding how serious researchers first tried to sort and study reports.
In Plain Sight: An Investigation into UFOs and Impossible Science by Ross Coulthart (2021)
Australian investigative journalist Ross Coulthart interviews military and intelligence sources about sightings and claims of secret government programs. It’s a fast, readable introduction to the modern “disclosure” debate, and an updated edition followed in 2023. Many of its biggest claims rest on sources that can’t be independently checked, so read it as an investigation in progress.
Imminent: Inside the Pentagon’s Hunt for UFOs by Luis Elizondo (2024)
Luis Elizondo, the former Pentagon official named in the 2017 New York Times story, gives his first-person account of the government’s UAP work and his claims about secrecy. It’s a memoir, not a neutral history. The Pentagon and Elizondo have given different accounts of the program, so it’s best read after Graff.
The “high strangeness” thinkers
These authors argue that the phenomenon may be stranger than “visitors in spacecraft,” and that it overlaps with folklore, religion and consciousness.
Passport to Magonia: From Folklore to Flying Saucers by Jacques Vallée (1969)
Computer scientist and researcher Jacques Vallée compares modern UFO encounters with centuries of folklore about fairies, spirits and sky visitors, and finds striking parallels. It’s a classic that changed how many researchers think about the subject.
Dimensions: A Casebook of Alien Contact by Jacques Vallée (1988)
An expanded take on the ideas in Passport to Magonia, and the first volume of Vallée’s Alien Contact trilogy. If you want Vallée’s argument in a newer, fuller form, start here instead.
American Cosmic: UFOs, Religion, Technology by D. W. Pasulka (2019)
Religious studies scholar Diana Walsh Pasulka looks at belief in UFOs as a new kind of religion, and follows scientists and tech figures who take the phenomenon seriously. One of them, called “James” in the book, was later publicly identified as Stanford immunologist Garry Nolan. Published by Oxford University Press, it’s academic but very readable.
Encounters: Experiences with Nonhuman Intelligences by D. W. Pasulka (2023)
Pasulka’s follow-up widens the lens to experiences people describe with “nonhuman intelligences,” from UFOs to angels to artificial intelligence. Reviews describe it as accessible but uneven, with a very broad definition of its subject.
First contact and the science of searching
The Eerie Silence: Renewing Our Search for Alien Intelligence by Paul Davies (2010)
Physicist Paul Davies, who chaired the SETI Post-Detection Taskgroup, asks why we haven’t heard from anyone, suggests ways to search beyond radio signals, and considers how humanity should respond to a real discovery. It’s the best book here on what first contact might actually involve.
Extraterrestrial: The First Sign of Intelligent Life Beyond Earth by Avi Loeb (2021)
Harvard astrophysicist Avi Loeb argues that ‘Oumuamua, the interstellar object spotted in 2017, may have been an alien light sail rather than a natural comet or asteroid. Most astronomers disagree, and published research has proposed natural explanations. It’s still a lively look at how a scientist argues for an unpopular idea.
Skeptics and the culture around UFOs
The Demon-Haunted World: Science as a Candle in the Dark by Carl Sagan (1995)
Sagan’s classic on scientific thinking includes a chapter on alien abduction stories, where he explains why he found the claims unconvincing. Even if you disagree, it’s the best toolkit for weighing extraordinary claims.
They Are Already Here: UFO Culture and Why We See Saucers by Sarah Scoles (2020)
Science journalist Sarah Scoles spends time with believers, researchers and skeptics to understand why UFO stories spread and what they mean to people. It’s sympathetic without being credulous, and a good choice if you’re curious about the community as much as the sightings.
Escaping the Rabbit Hole: How to Debunk Conspiracy Theories Using Facts, Logic, and Respect by Mick West (2018)
Mick West is known online for analyzing UAP videos. This book isn’t mainly about UFOs, but it’s a practical guide to how people fall into, and climb out of, conspiracy thinking. Useful balance for anyone reading deeply in this field.
A beginner’s reading path
- Get the testimony: Kean, UFOs: Generals, Pilots, and Government Officials Go on the Record.
- Get the history: Graff, UFO.
- Hear the insiders: Coulthart, In Plain Sight, then Elizondo, Imminent.
- Go stranger: Vallée, Passport to Magonia or Dimensions, then Pasulka, American Cosmic.
- Think about contact: Davies, The Eerie Silence.
- Test it all: Sagan, The Demon-Haunted World, and the free AARO report linked above.
The U.S. government also studied psychic spying during the Cold War. If that history interests you, see our guide to remote viewing books for beginners. And if you’re drawn to “ancient visitor” theories, read what archaeologists actually know about Göbekli Tepe and the ancient “handbag” symbol first.
Prefer fiction? Handbags of Time is an archaeological mystery and first-contact thriller in progress from this site.
FAQ
What’s the best UFO book for beginners?
Leslie Kean’s UFOs: Generals, Pilots, and Government Officials Go on the Record (2010) is the most common starting point because it centers on firsthand accounts from credible witnesses. For a full history, add Garrett Graff’s UFO (2023).
What’s the difference between a UFO and a UAP?
UFO means unidentified flying object. UAP, now used by the U.S. government, means unidentified anomalous phenomena. It’s a broader term that also covers objects seen in space or underwater. Neither term means “alien.”
Has the U.S. government confirmed aliens?
No. AARO’s 2024 historical report found no evidence that any UAP sighting represented extraterrestrial technology, and no evidence that the government had recovered such technology. Some authors on this list, including Coulthart and Elizondo, dispute that conclusion.
Are there good skeptical UFO books?
Yes. Carl Sagan’s The Demon-Haunted World and Mick West’s Escaping the Rabbit Hole teach you how to weigh claims, and Sarah Scoles’s They Are Already Here looks at UFO culture with an open but critical eye.
