Designed to explore the historical similarities and contrasts, ethnic diversity, and interactions between Brazil and the United States, this site contains almost 1,000 images from the rare book, manuscript, map, print, and photographic collections of the Library of Congress and the National Library of Brazil.

The site includes letters (including letters from Thomas Jefferson concerning the independence of Brazil), illustrations, 18th-century maps, and other textual items, including poetry.

The sources are available in five categories: "Historical Foundations," "Ethnic Diversity," "Culture and Literature," "Mutual Impressions," and "Biodiversity" (right now, only the Historical Foundations section is completed). The site is viewable in both English and Portuguese, and is appropriate for high school and college students, as well as teachers and researchers.
