This document provides an overview of the book "This Land That I Love" by John Shaw. The book tells the dual biography of the songs "This Land Is Your Land" by Woody Guthrie and "God Bless America" by Irving Berlin. It explores how the songs emerged from the Great Depression and WWII eras. Though Guthrie and Berlin presented different political views in their songs, Shaw's book finds they had more in common in their backgrounds, both rising from poverty. The book also sheds light on the deeper history of American patriotic and folk music traditions that influenced the two songs.
