My interest in the U.S. presidents started with my love of American history. The two subjects are forever entwined. But then it wasn't enough for me to simply know about the greats—Washington, Lincoln, both Roosevelts—I wanted to know about all of them, their dates in office, their order respective of each other, and other fun facts. This book from the Smithsonian Institute scratches that itch and more.

This encyclopedia is both an in-depth look and a jumping off point. I highly recommend taking one of the many tidbits within that you find interesting and exploring the topic further. ( )
