Sources Cited (Update 11/13/15)

Most posts about the Man from Taured don't cite any sources, but those that do usually include the following two:

The Directory of Possibilities, 1981
The Directory of Possibilities is the most often cited source of the story. It is basically an encyclopedia of strange/paranormal/weird events. The man from Taured gets only one sentence in the book, on page 86. It's in Part 3, "Strange Creatures and Unusual Events," under "Appearing People."

And in 1954 a passport check in Japan is alleged to have produced a man with papers issued by the nation of Taured.

To say this is disappointing is to say the least.

Strange but True: Mysterious and Bizarre People, 1999
I haven't yet read this one, but have requested it from another library in my system. I am expecting essentially a retelling of the same story that's everywhere on the Internet, but I'm hoping for another source to hunt down.

Update - I received this book today, November 13, 2015. The book is copyright 1998, not 1999. The Man from Taured shows up on page 64, chapter entitled "The Alencon Spaceman." 

In 1954, the Japanese authorities detained a man trying to enter the country with a passport that revealed he was from an unheard country named "Taured". A thorough check was made by the customs officials to see if there was such a place anywhere on Earth, but they drew a blank. The stranger refused to throw light on the whereabouts of the mysterious nation of Taured and quickly left Japan.

Interestingly, the man doesn't disappear in this story (copyright 1998), he just "left," which seems unlikely.

Frustratingly, the author, Thomas Slemen, does not cite any sources in his book at all. If his source was The Directory of Possibilities - he certainly expanded upon that one sentence. If it wasn't - where did the story and the extra details come from?
