From the Wikipedia page

The Mário de Andrade Library (in Portuguese: Biblioteca Mário de Andrade; BMA) is the largest public library in the city of São Paulo, Brazil. Founded in 1925, with a donation of holdings by the library of the city's Câmara Municipal, it became one of the most important cultural institutions in Brazil, as well as one of the leading research libraries in the country. It is named in honor of Mário de Andrade, one of the founders of Brazilian modernism. It is housed in an Art Deco building in the historical downtown, considered one of the icons of this style in the city.
