The Field Guide to Bigfoot and Other Mystery Primates  by Loren Coleman and Patrick Huyghe

From the book... We are not alone. If there is any truth to the testimony of eyewitnesses worldwide, we appear to live amid a variety of humanlike and apelike creatures whose existence has been largely ignored, forgotten, or denied, at least in recent history. Despite the crowding of the earth's surface with our species and the encroachment of Homo sapiens into the mountains, wildernesses, and wild places around the world, there is apparently ample room left over for our elusive cousins to hide. And they have done just that-for the most part. But as the reports of encounters accumulate, it has become increasingly clear that an understanding of these creatures lies not in myth, folklore, and legend, but, ultimately, in reality... Just as Linnaeus, in 1735, envisioned bringing order to the chaos that reigned between cultures, nations, languages, and different authors with regard to life-forms in the natural world, we hope this field guide brings some order to the mass of reports of seemingly unrelated and diverse species of unknown hairy hominoids seen worldwide.
