Also, it you want this article to be old,old, and stuffy,  limited, then ask for "mainstream"
sources. Those all have their heads up their ***es and they all are terribly biased at the onset.
They predetermine their outcomes. Have to, to keep their jobs!  Same goes for most tv docs. 
They are instructed by their network, "This is how your show will look." One semi-decent one,
just semi, was Sasquatch: Legend Meets Science  by White Wolf Productions, now on dvd.
