Since research in Brazil is very interdisciplinary, there is not just one section of the library collection to refer to. The best option is to use the library catalog, called OneSearch, to search for your topic by key word. You can then add AND Brazil to your search terms to further narrow your results.
Your search might look something like this:
Sustainable tourism AND Brazil
Women's health AND Brazil
Economic development AND Brazil
Once you find the book, use the call number to find it in the stacks, or click the link for full-text if it is an ebook.
