I was also pleased to learn through reading the Acknowledgments page how many scholars Fleming consulted with and how careful she was to have the entire contents of her book fact-checked before publication. I would recommend The Lincolns: A Scrapbook Look at Abraham and Mary as a reference book for tweens (ages 8-12), as well as teens and adults. It's the kind of book readers will enjoy dipping into again and again.
For more recommended books, see Children's Books About Abraham Lincoln. You might also show your kids images of the actual Emancipation Proclamation signed by Lincoln and share Facts About the Emancipation Proclamation.
