Well, on a hunch I've started looking up keywords and names central to the NWO UFO conspiracy. I'm looking them up in well-respected tomes - one would expect to find at least a passing reference to the conspiracy theories which have abounded now for hundreds of years, with specific reference to the following keywords:
I have only just started doing this, and it's obviously a mammoth task, so please send in what you find - but you get the idea, there's not a lot to find, or I wouldn't be asking for contributions.
In fact I searched on the above terms on Xrefer, which bills itself as follows:
"xrefer is a giant online reference library, in fact, all the reference books that you'd expect to find in any good reference library. xrefer includes encyclopedias, dictionaries, thesauri and books of quotations, not to mention a range of subject-specific titles covering everything from art to accountancy and literature to law."
...but it still hasn't even heard of the keywords "Bilderberg" or "Weishaupt", and has only oblique references to trilateral anything.
It has heard of Illuminati, but no information is given about any such "societies" that may have existed under this name.
I'll add to this page as time passes.
