The bibliography is a nearly exhaustive listing of books and articles in American libraries which make some explicit reference to the Portuguese in the United States. The 800 entries, citing sources published during the 20th century, are mainly written in English or Portuguese, although a few are in German, French, and Spanish. Coverage extends from the discovery of North America, or at the turn of the 15th century, to the middle of the 20th century, and from New England to Hawaii. The documents include histories, population reports, psychological and physiological research reports, and novels. They are presented alphabetically by author in two main sections: "Portuguese in the United States, Including Hawaii" and "Portuguese in Portugal." In the first section, entries are further divided according to six geographic regions. A seventh subsection lists fictional literature depicting Portuguese immigrants in the United States. Section two, intended as a supplement to Section one, contains seven subsections on economic conditions and social welfare; general descriptions of the country; and popular creeds, customs, and language. The document does not contain biographies of particular Portuguese-Americans or by-laws and reports of Portuguese-American fraternal organizations. (Author/AV)
