A reddit user ConcernedEarthling just posted his collection of UFO books in digital edition.
This is what he wrote:
This collection of books is what I have accumulated and organized over time to supplement my physical library at home, and it has been a useful collection to refer to others who have wanted some relevant reading.
It is actually one folder of a larger collection of online UFO materials, in what I call the UFO Reading Center, and it contains organized collections of magazines, studies, papers, and other materials. The entire collection is hosted on Google Drive..
I hope this is a useful and plentiful resource for those of you who may not have stumbled on it yet.
In this digital era the most valuable images of UFOs are those from the past and I mean before the digital public use of techniques that shows UFOs and/or ETs designed through software.
