Web Resources
There is a rapid turnover of UFO material on the Internet. Many links to material on UFO websites quickly become out of date. Therefore, instead of giving many links to specific webpages I have instead included below a search box which can be used to search various leading UFO websites at the same time. You can then click on tabs at the top of the search results to list only results from forums, only results from websites I have labelled as "skeptical" etc. I have included tabs for a couple of specific websites that I find particularly useful, including the valuable archives of the UFO UpDates email discussion List. The relevant websites are all listed in the discussion of the "UFO Searchillion" search engine in Section 2.4 of the "Free UFO Researcher Starter Pack" and continues to evolve...
The relevant search box is one of the two main tools on this website which are intended to help reduce the amount of reinvention of the wheel within UFOlogy. The other main tool is the collection of tables of references to discussion of UFO incidents, personalities and other matters in various books. Those tables can be sorted by author, length and date. I hope these tools are useful.
Book References
Image/text of letter in Hynek, J Allen in his “The UFO Experience” (1972) (available on Amazon USA and on Amazon UK) (in Chapter 11) at page 167 of the Henry Regnery hardback edition (with same page numbering in the Abelard-Schuman hardback edition) at page 189 of the various Ballantine paperback editions, at page 209 of the Corgi paperback edition.
The table below includes references to relevant discussions in UFO/SETI books noted by Isaac Koi during a review of approximately 963 UFO/SETI books during the period 2003-2006 (with a few later additions). The table can be sorted by author, date and length of discussion by clicking on the relevant word in the top line of the table.
Many of the tables of references on this website are considerably longer than the references to books found on most other UFO websites. Indeed, some are probably the longest that have been collated in relation to some events and personalities. Together with the "UFO Searchillion" search box, I hope that these tables are found to be a useful contribution to UFOlogy.
