Arquivo Edgard Leuenroth

From the Wikipedia page

Arquivo Edgard Leuenroth is a historical and media archive that is maintained by the Brazilian State University of Campinas (Universidade Estadual de Campinas—Unicamp), located in the city of Campinas in the state of São Paulo, Brazil. It was started by a donation of the media collection assembled by Brazilian anarchist journalist and publisher Edgard Leuenroth (1881 - 1968).

The Arquivo Edgard Leuenroth has the largest collection of materials regarding social movements, counterculture, and other alternative cultural movements in Brazil. This collection is, therefore, very much appreciated by researchers from all over the world, because it presents a non-official view and understanding of Brazil in the twentieth century. Among others, the Feminist Movement (or Movimento Feminista) and the Homosexual Movement (or Movimento Homossexual—in this case, the Grupo Gay da Bahia), are among the many collections being maintained by the Arquivo Edgard Leuenroth of the State University of Campinas.

The collection includes 280,000 documents, 28,000 books, 854 videos, 289 films, 1,419 audio recordings and 45,000 photographs.
