I had the chance to finally get Do Abominable Snowmen of America Really Exist? last month at the Ohio Bigfoot Conference. My copy is even signed - not by Roger Patterson, but by Bob Gimlin, the next best thing.
It even has the latest facts! : )
In his book Patterson talks about some of his personal research into the Bigfoot mystery and also reprints many newspaper and magazine articles about old sightings and from the Bigfoot craze in Northern California in the late '50s and early '60s. Accounts include the story of "Jacko", a young Bigfoot supposedly captured in Yale, British Columbia, the Bluff Creek prints and sightings, William Roe's encounter, Albert Ostman's kidnapping, tales of the Yeti, and lots of other sightings. Some of them I hadn't heard before.
While it's a bit outdated, I would definitely recommend Patterson's book to all Bigfooters just because he wrote it. And, it's a good book. You can buy it on Amazon, but beware, it's expensive!
My next book review on Tyler's Cryptozoo will be In Search of Lake Monsters be Peter Costello. Other upcoming summer reviews include Chad Arment's The Historical Bigfoot, and possibly Varmints: Mystery Carnivores of North America (also by Chad Arment), In the Domain of the Lake Monsters by John Kirk, and From Flying Toads to Snakes With Wings by Karl Shuker.
