Acervo Folha is a digitized compilation of the newspaper Folha de S.Paulo. With 1.8 million pages, the newspaper collection posted on the internet is an invaluable historical source that covers 90 years of editions published about Brazil and the world. The service was launched in February of 2011.

The site brings complete series for three titles: "Folha da Noite", the original daily evening paper, from 1921; "Folha da Manhã", the morning edition created in 1925; and Folha de S.Paulo, that resulted from the merger, since January 1, 1960, of these two daily papers and "Folha da Tarde" (1949-1959). The service allows one to locate copies by the day of publication or to perform detailed searches by key words.
