This paper studies the co-production relations between knowledge and the space present in the dynamics of communication in journals. With an analysis of the Geography of the Objects of Study in the articles published in Caldasia, 1940-1952, a relation is observed between the editorial and scientific objectives that come together in the journal and their spatiality. It explores (i) how the scientific objectives of the Institute of Natural Sciences and Caldasia´s editorial policies converge; and (ii) the coexistence of divergent visions, on the one hand the journal´s director and on the other international researchers as to the geographical scope of the scientific objectives of the journal.
