    On the one hand, we see our country as a haven for the poor and oppressed; anyone, no matter his or her background, can find freedom here and achieve the “American Dream.” On the other hand, depending on prevailing economic conditions, fluctuating feelings about race and ethnicity, and fear of foreign political and labor agitation, we set boundaries and restrictions on who may come to this country and whether they may stay as citizens. This book explores the way government policy and popular responses to immigrant groups evolved throughout U.S. history, particularly between 1800 and 1965. The book concludes with a summary of events up to contemporary times, as immigration again becomes a hot-button issue. Includes an author’s note, bibliography, and index.

    That’s the inspiring message of this lively, collectible picture book biography series from New York Times bestselling author Brad Meltzer. Kids always search for heroes, so we might as well have a say in it, Brad Meltzer realized, and so he envisioned this friendly, fun approach to biography for his own kids, and for yours. Each book tells the story of one of America’s icons in an entertaining, conversational way that works well for the youngest nonfiction readers, those who aren’t quite ready for the Who Was series. Each book focuses on a particular character trait that made that role model heroic. For example, Abraham Lincoln always spoke up about fairness, and thus he led the country to abolish slavery. This book follows him from childhood to the presidency, including the Civil War and his legendary Gettysburg Address. This engaging series is the perfect way to bring American history to life for young children, and to inspire them to strive and dream.
