The document discusses how textbooks used in segregated East Texas schools in the 1950s-1970s distorted identities and reinforced racism. It examines textbooks like Treasure Gold (1964), Finding New Neighbors (1957), and Days of Adventure (1962) that largely excluded or stereotyped black people. The textbooks are criticized for how they failed to include blacks in history or portrayed them with negative stereotypes. Illustrations in books like Treasure Gold depicted white men in roles of leadership and accomplishments while labeling other nationalities and races as "other".
