Note 1: Swamp Gas & Venus Not Included. Note 2: The sectors other than Axis WWII / Foreign Aircraft and Spiritual are, in my estimate, much smaller than depicted in these two charts. They are enlarged for the purpose of enhancing the visual clarity of the chart. The purpose here is not to be numerically precise but only to illustrate that the UFO phenomenon is multifaceted, requiring more than one theory to cover all the bases. For a good laugh, see the U.S. Air Force Aircraft Identification Chart: http://i41.tinypic.com/2m6l3td.jpg

 

 

 

 

*NOTE: These charts reflect a mixed-solution concept roughly matching my reading of UFO literature over 50 years. They are not a statistical summary of a rigorously conducted scientific survey.

Ufology 101—7 Quick Steps to UFO Expertise:

 

 

 

 

1.     The following free e-books are a particularly excellent way to begin UFO study. NICAP offers The UFO Evidence, by Richard Hall & The Challenge of UFOs, by Charles Maney & Richard Hall. The Hathi Trust digital library contains Edward J. Ruppelt's classic The Report on Unidentified Flying Objects. Nothing you can buy at any price goes more to the heart of the UFO phenomenon than these three free e-books. In fact, let’s make it four, with Francis Ridge’s book, Regional Encounters, also a core resource:

 

http://babel.hathitrust.org/cgi/pt?id=mdp.39015040282959;view=1up;seq=19

http://www.nicap.org/ufoe/UFO%20Evidence%201964.pdf

http://www.nicap.org/books/coufo/coufo_complete.htm

http://www.nicap.org/regenc/regional.htm

 

Why not round it out at five? The Congressional Research Service Report, 83-205, The UFO Enigma, by Marcia Smith and George Havas, is also a good starter text:  http://www.nicap.org/docs/TheUFOEnigma.pdf

 

2.     Of core value to the subject is the work of Sign Historical Group, including their resource page as well as the Project 1947 main site. These projects are still young and growing, but they are the work of serious historical researchers. The interface is a tiny bit cumbersome, but the content is excellent and well worth the investment—certainly the highest quality commentary content on the Web, richly garnished with a solid core of historical fact. If you dig deeply you will find some bad links that have gotten out of date, but there is plenty of good stuff still working. Don’t give up on these sites until you have worked your way through them. One item they have posted that is worth a look is Dr. Paul E. McCarthy’s PhD dissertation on the politicking that went on behind the UFO hearings and conferences of the 1960’s, Politicking and Paradigm Shifting: James E. McDonald and the UFO Case Study: http://www.project1947.com/shg/index.html http://www.project1947.com/shg/resource.htm  http://www.project1947.com/shg/mccarthy/index.html#shgintro.

 

3.     After getting SHG and Project 1947 under your belt, spend time at the NICAP, CUFOS, MUFON,  NUFOC, & CUFON Websites (this study guide has no test questions—go where you want, sleep late, bring snacks, no problem):

 

http://www.nicap.org/

 

http://www.cufon.org/

 

http://www.mufon.com/

 

http://nationalufocenter.com/

 

  

4.     Filer’s Files (NUFOC) Website is the next stop. NUFOC offers the current parallel to NICAP’s historical case archives, so spend some time there to get up to date on what is happening now: http://nationalufocenter.com/category/filers-files/. Note: It strikes me that some of the modern reports are completely or substantially fabricated. This seems true wherever you go to retrieve recent reports; it is not unique to Filer’s Web site. In fact, Filer’s Files may be one of the better Web sites on that criterion, with fewer falsified reports—and most mainstream sites are equally good. The fringe and strictly bloggish type pages don’t seem nearly as legitimate. Some of the You Tube films of alleged UFOs appear to be fakes as well, though the interviews on You Tube are generally excellent. Yes, there were fraudulent reports in the old days as well, but the modern culture seems to have produced a higher frequency of them for some reason. Again, one can’t blame the Web site owner for false submissions, but it is something to keep in mind while evaluating the reports.

 

5.     Next, review the APRO bulletins posted on the Open Minds Website at http://www.openminds.tv/ufo-files/ to get a feel for the content and patterns of UFO reports from prior decades and some of the history of the main investigative groups during the golden age of UFOs in the 1950s & 1960s.

 

6.     For the best printed introduction to the subject of UFOs, get a copy of Jerome Clark’s The UFO Book: Encyclopedia of the Extraterrestrial. (Visible Ink Press, 1998) or one of Clark’s other encyclopedic works. Prior to digging into the depths of the encyclopedia, read Jay David’s excellent little book, The Flying Saucer Reader and Don Berliner’s UFO Briefing Document, similarly small but with high quality case selections. These aren’t the only references you will need to become expert, but they make a darn good start.

 

7.     To round out things a bit and for some excellent quality reading material, also buy or borrow a copy of the following books. There are additional free e-books linked in the E-Books section of this Web page down below the bibliography. The Cases, History, & Timelines sections also offer good free reading materials.  [NOTE:  While these are some of the best books, by recommending them I am not claiming everything in these books is true, and I frequently find myself unable to share the authors’ opinions on such things as outrι activities at underground bases, government cover-ups of alien contact, etc.]

The first thing to do if you are having abduction experiences is to pray for deliverance and see a priest to rule out the supernatural. Don’t forget the sequel, An Exorcist: More Stories.)

 

8.     Busy and just want the bottom line? Looking for the answer about UFOs? Here is the book that I believe convincingly points at the final answer on UFOs, Henry Stevens’ book, Hitler’s Flying Saucers:

PS: Don’t miss the free UFO trivia game, UFO Hunt, near the bottom of this page after the book list!

 

*PLEASE NOTE: While I can recommend all of the books in this frame as quality books, good reads with useable info, I don’t agree with all their conclusions. Specifically, the government conspiracy angles strike me as mere conjecture devoid of fact, and ET, in my opinion, is not the primary source of UFO sightings, though there may have been some ET sightings and encounters. I also don’t believe there are living occupants in typical UFOs, though robots are possible—the heat, radiation, and gravity stress are too severe. Many of the books in the bibliography below, unfortunately, are not quality books. Some (in my opinion) are patently false; some are almost certainly disingenuous; some are spiritually dangerous (telepathic contact often leads to demonic attachments); and others are flat out ridiculous! They are all entertaining, however, and they are legitimate parts of the cultural history of UFOs—they have their own readerships. That is why I have included all types of UFO books, even though I cannot personally endorse many of them as reliable content or quality writing.

 

ENJOY THE LIST!

UFO Bibliography

 

Many UFO books were published by several different publishers. Only one version of each book is listed unless something is known to have changed. I have not indicated the number of pages for these books, so you will want to check before ordering a book from an online source. The size of these books ranges from 5 page pamphlets to over 600 pages. A few articles are also listed, and they may range from a single page letter to the editor to ten, fifteen or more pages. The average article runs two to seven pages long.

 

If you would like to know if your local public or university library has a book before you buy or just for purposes of optimizing a visit to that library, visit the WorldCat Web site first. WorldCat has 2 billion or more books listed. Enter the title, author, or subject key words for the book(s). Click on the book’s name in the list of books and review the lower and right-hand section of the page to see the libraries near you that have the book. There may also be a source for an e-book: http://www.worldcat.org/. 

 

Which Are the Best Books? I have highlighted in grey the books that should offer at least something of value on the subject. This doesn’t mean I agree with the author’s logic or conclusions; I usually don’t. It doesn’t mean I believe the purported facts contained in the book are true, or even that I think the author is trying to be honest. The grey highlight is not a personal recommendation. It only means a reader is either likely to learn something of use by reading the book, have an entertaining read, or perhaps get some practice reading between the lines to discover the politics that are involved in ufology—a valuable lesson in itself. A book may be highlighted because it is an authentic example of one of the classic points of view or of a specific genre—and for no other reason. These genres and points of view may involve the assumption of a theory of UFOs that I feel is completely wrong, but they nonetheless have social, psychological, political, or historical value.

 

Some of my personal favorites are listed below in the white intro frame, but not all. The topic of which books are best is continued at the bottom of the blog in the right column, at which point I do give personal recommendations.

 

Foreign language book titles follow different rules for capitalization. I try to use the rules the Library Science Department at Butler University have posted on their Web site at http://libguides.butler.edu/content.php?pid=1873&sid=9039, but don’t always get it done right. The “juvenile readers” flag at the end of a book entry indicates that the book targets readers from pre-school to high school.  Check the vendor listing or book jacket for more specific age recommendations. While I tried to get as many adult-reader UFO books as possible into this list, the representation of books for juvenile readers is a much smaller fraction of what is actually out there.

 

The translations of book titles from the German language into English are my own. My apologies for any errors. The same goes for the handful of titles from Spanish or French that I attempted to translate into English.
