The libraries of Rio de Janeiro are a jewel of inestimable value for conserving the city's literary heritage, and for their formative role in its physical, social, and cultural development.

One such institution is the Fundação Biblioteca Euclides da Cunha (Euclides da Cunha Library), which is part of the national library and is located in the Centro neighborhood in the city centre. - Not only does its name pay homage to one of the most important writers in the city's development, a journalist, sociologist and engineer who lived between 1866 and 1909, but it also contains 150,000 works, including important national documents, bibliographies, biographies, maps, atlases, newspaper clippings, magazines and scholarly articles.
