1940. 558p. by Percy Alvin Martin. 

"Who's Who in Latin America" aims to enhance inter-American cultural relations by providing updated biographies of prominent Spanish Americans and Brazilians. While maintaining the general scope of the first edition, it includes over four hundred new entries and a new section on Haiti, reflecting the editor's commitment to accuracy and comprehensiveness. The biographical sketches focus on pertinent facts, omitting irrelevant details, and include bibliographical material to showcase the works of the individuals featured.

The editor acknowledges the challenges in including non-Latin Americans who have contributed to the region, ultimately deciding to limit entries to citizens by birth or naturalization of the relevant countries. Efforts were made to update existing biographies through correspondence, but gaps remain due to unresponsive individuals. The editor expresses gratitude to contributors and welcomes suggestions for future improvements, emphasizing the ongoing need for a comprehensive resource on influential figures in Latin America.
