NA Birding companion guides comparison (1 Viewer)

I've created a comparison of Kenn Kaufman's "Lives of North American Birds", National Geographic's "Complete Birds of North America", and Pete Dunne's "Essential Field Guide Companion".
Here's the link:

As I have time, I'm going to try to improve the layout and look of the page.
Please reply with any constructive criticism, such as things that could be done better, or additional info you would like to see included.
This is the first time I've done anything like this, so please be kind

hope you find something useful,

Good idea to list publishing year. I like the Kaufman book, there is nothing like it. But the age is showing a bit. His book was a spinoff from a CD ROM project.
