America Is in the Heart, sometimes subtitled A Personal History, is a 1946 semi-autobiographical novel written by Filipino American immigrant poet, fiction writer, short story teller, and activist, Carlos Bulosan.
 The novel was one of the earliest published books that presented the experiences of the immigrant and working class based on an Asian American point of view and has been regarded as "[t]he premier text of the Filipino-American experience."
 In his introduction, journalist Carey McWilliams, who wrote a 1939 study about migrant farm labor in California ("Factories in the Field"), described "America Is in the Heart" as a “social classic” that reflected on the experiences of Filipino immigrants in America who were searching for the “promises of a better life”.
Salom Rizk (a.k.a. Sam Risk, born 15 December 1908 in Ottoman Syria, died 22 October 1973 in Silver Spring, Maryland) was a Syrian-American author, best known for his 1943 immigrant autobiography, "Syrian Yankee", perhaps the best-known piece of Arab American literature in the middle part of the century.
 The book has been called "a classic of the immigrant biography genre", especially for the way Rizk's story portrays the American Dream and the virtues of cultural assimilation at the expense of his home country, which he finds loathsome when he returns for a visit.
 Rizk became well-known enough that Reader's Digest sponsored him on a lecture tour around the United States as "the quintessential American immigrant".
 He also sponsored a drive for the Save the Children Federation, using advertisements in such magazines as "Boys' Life" to request families send their extra pencils, so that these could be donated to needy school-children around the world as a way of promoting freedom and democracy and fighting tyranny.
