I love DK publications. But this one doesn't work. It's a copy of information from the Smithsonian and it is designed to read opposing pages as a single graphic. So you're scanning right-left-up-down trying to read even a small caption on a photo that is off the screen because you had to increase magnification so much to be able to read the teeny-weeny text. Wish I could get my money back...a really impossible read on Kindle.
