I have looked over the internet to offer you a place to find yours and the websites www.textbookrush, www.walmart.com and http://www.christianbook.com are the least expensive. The book is available in older editions on Etsy.
I work in a very wealthy neighborhood and had to tell the college age son NOT to pet the stray dogs. They were coyotes. They had been spotted in the county and were usually seen on night security cameras. Now, two years later they are in the neighborhood and there are missing cats and dogs. It's one thing to have the occasional bear in the trash. They forage then move on, but the coyote stays. They do not fear humans like the local red fox. They don't care about your attachment to fluffy and they are not dogs. With a good full color guide, they are also easy to spot and report.
This book or one very similar should be in your library. It is good to have hard copy reference books on hand in a grid down situation to help you identify plants and animals in your region. Early man found edible fruits and vegetation by tasting them sometimes suffering the consequences of also finding toxic plants, by tasting them! You don't have to put these plants in your mouth first when you have a good guide. If you are confident that you do not need a guide to animals of this continent, please allow me to suggest you find a field guide to plants in your region.
Also available through Walmart and other outlets is this helpful survival guide, for a very affordable price of $4.79:
As a general survival guide, this SAS guide is a good one covering many climates and topography. What puts this in the field guide category, is it's sections on edible wild plants and it's easy to understand guidelines for determining if a plant is safe to eat.
Get a good guide for your region or one like these that covers your continent. But, browse the web, find a guide that fits your needs and covers the most in the way you find suited to you. I have the SAS guide in a Flick Book. I have a text book for medicinal plants of the Southern United States and now, I have the Reader's Digest North American Wildlife. That is enough for me. If I find another set of similar books, they will end up as gifts.
