[The Fiocruz archives: sources for research on science and health during the military dictatorship (1964-1985)].

The scope of this paper is to analyze the relationship between the country's political redemocratization process from the 1980s onwards and the issue of identification, preservation and access to the archives of information and security bodies that worked to combat the opponents of the authoritarian regime during the military dictatorship (1964-1985). It addresses the dictatorship's action on university and scientific institutions, to highlight the importance of the archive of the Oswaldo Cruz Foundation, as well as the personal files maintained by scientists and donated to Casa de Oswaldo Cruz. It features archives and collections organized and available for public consultation, which can serve as research sources for historical studies on science and health during the dictatorship.

An archival approach: the documents of a biomedical sciences laboratory.

This article addresses archival methods, techniques, and practices for managing documents generated by scientific activity, using field research carried out at an Instituto Oswaldo Cruz laboratory at the Fundação Oswaldo Cruz as a reference. Based on an analysis combining an archival studies approach with elements of the sociology of science, we believe that the models and instruments of archival knowledge are subordinate to the assumptions of historical research or social memory. They also serve a technical rationality aligned with empirical organization practices that confront the more complex archival reality, leading archival science to negate its foundations and theoretical principles.

[Malaria in pictures: images from Brazil's public health campaigns in the first half of the twentieth century].

The article discusses a set of pictures that illustrate public health activities, practices, and campaigns against malaria in Brazil from 1918 through 1956. Exemplary of certain key moments in this history, the illustrations belong to three archives from the Casa de Oswaldo Cruz/Fundação Oswaldo Cruz collection: Arquivo Belisário Penna, Arquivto Fundação Rockefeller ("Serviço de Malária do Nordeste" series), and Arquivo Rostan Soares. The article links these photographic records to their specific historical-public health contexts and to the campaign models and strategies represented by each archive.
