Autumn Williams, for those that don't know, is a Bigfoot researcher. She is not a UFO researcher. Her new book is Enoch, about the Skunk Ape/Bigfoot as well as the nature of Bigfoot research. I mention the book here because, even though it's not about UFOs, I saw many parallels to UFO research! So many times I thought, when reading Enoch (which is excellent) replace "Bigfoot" with "UFO."
Examples: treatment of the witness, rejecting parts of witness experience because it's just too weird for the researcher to accept, credibility issues, the role of researcher and witnesses, and, in relation to each other (so many times, even if it's not intentional, there's a power thing going on, researcher is the "boss," the witness is the lowley informant), researchers as witnesses themselves...
Another important point Williams brings up is why? And what... what do you, as researcher or witness even or investigator, want to gain from all this? Proof? Evidence? Vindication? The journey itself, the process? Hoping to get an in with Big Science?
Of course Williams is asking these quesitons in context of Bigfoot, and not UFOs, it's just that I saw so much there that could be applied to this field as well.
