Some books lend themselves especially well to trailers. Rare: Portraits of America's Endangered Species, presented by National Geographic wildlife photographer Joel Sartore, offers one good example. Sartore's footage of these rare creatures, all shot against a simple white background, leaves you wanting more. Fortunately there's plenty more on the book's site, including a nice behind-the-scenes video, and an extensive gallery (you may need to scroll down). Be sure that you don't miss the ocelot.
If you've gone through the site and you're still not satisfied, there's always the Smithsonian Institution's new wildlife photo archive, which we've been lost in all week.
