The Golden Book on Reptiles and Amphibians is very well written, well illustrated, and is just one marvelous little book.
When I was a young boy, around First Grade, my mom (who was a librarian at the time) got me all of the different Golden Guides on nature, including the one on reptiles. I used to read this snake, frog, lizard book over and over again, and along with the other Golden Guides, it helped shape my life and my lifetime love of nature...especially for snakes...and lizards.
Today as an adult, I still go out to find and see snakes, lizards, frogs, turtles, salamanders, skinks....this little book was the impetus for a lifelong love of reptiles and amphibians.
I am also a writer (Allergy-Free Gardening, Birthday Boy, Safe Sex in the Garden, The Highway Naturalist, etc..), and a former science teacher, and I recommend buying and giving these books as presents to all children.
You might well strike a spark that will trigger a life long appreciation and fascination with nature.
This book might well also be interesting and useful as a first book on snakes for anyone with a budding interest in wildlife, lizards, fishing, nature. But as with all the Golden Guides....these books are wonderful tools to create interest in young kids.
For adults or teenagers I would recommend a reptile/amphibian book such as one of the Guides from Robert Stebbins, but for kids...the Golden Book is a darn good one to start with. Get each youngster his or her own book, and encourage them to write in the book, to make notes, to jot down dates as to when they first saw each species. This is a very fun, fine book!
