Mário de Andrade Library

The Mário de Andrade Library 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.

Mário de Andrade Library was the first Brazilian public institution interested in acquiring modern works of art of local and foreign artists. It has been a member of United Nations depository libraries system since 1958, though it started receiving UN material nine years earlier, in 1949.
