Good list. Thanks for sharing it. There are a couple on there I haven't read yet.
I offer a list of 4 to people who are new to the interest. If I had to clear my shelves, these would also be the ones I keep. Some people will find some controversial ... my intent is to start people out understanding that there are many perspectives. As I've said many times, 'til we know what is, we don't know what isn't. We need a broad perspective. My list overlaps yours partially.
1) Sasquatch: Legend Meets Science - Jeff Meldrum
2) Abominable Snowmen: Legend Come To Life - Ivan Sanderson
3) Enoch - Autumn Williams
4) The Locals - Thom Powell
After .. some years .. of being fairly absorbed by the topic I find that other books don't add anything I don't find in those 4. Yep, more repetitions, but truly the same content, just over and over and over, nothing new that generates an "ah-hah" moment that I otherwise missed. How many instances of bigfoot crossing the road do you need to realize sometimes bigfoot crosses a road? Do I need to read every single "crossing the road" instance or do I just need to pay attention while reading ONE? And so on. The only thing additional readings offer to me is locations. From those I can derive patterns and maybe identify locations with a better than average probability of a repeat.
... my twisted view on the subject anyway.
While it's not on my short list, Barbara Wassum's book is particularly interesting because one of her contributors, Jack Woodruff, interviewed a bunch of people I knew about through other .. paths. Folks my grandfathers on both sides knew. I knew of some of the reports through the Bigfoot Bulletin before reading Barbara's book. I'm sure you know she wrote another book as Barbara Butler. I have a copy of an unfinished manuscript of a 3rd book she was working on which I got from her daughter. Anyway, I'm happy to see you mention her. Most don't.
One other, for the enthusiast, especially Oregon / Washington, is "In the Spirit of Seatco" by Henry Franzoni. Some seems off the deep end but his maps and his place names analysis is pretty good. He observed that reports concentrate in late summer / early fall .. say late August to early-mid September. That is precisely what I observe in "my" area. If you're not in the woods looking at that time, you might as well take up golf instead of bigfooting.
