Hundreds of thousands of documents are available for research on Latin American, Caribbean, and Latino/a topics. From the Ancestry homepage on the CCSU database website, go to Card Catalog under the search tab. Hundreds of thousands of documents are available here for family history but also for other types of research. For example, the entire 1930 manuscript census for Mexico is available, as are the manuscript censuses for Puerto Rico for 1910, 1920, 1930 and 1940. For Latino/Latina communities in the U.S. prior to 1940 there is extensive information, including on military service in World War I and World War II. Because of privacy laws, most documents date from 1940 or before.
For Latin American, Caribbean, and Latino/a studies, see especially the extensive documentation on U.S. intervention in Latin America since 1945, such as on Chile, Guatemala, and Colombia. The documentation is constantly being updated through Freedom of Information requests and suits.
