The present article is the fruit of research on the circulation of Brazilian books from the "Atualidades Pedagogicas" collection at the "Biblioteca Museu do Ensino Primario" (Primary Education Museum-Library) in Lisbon. This library was headed by Adolfo Lima, one of the exponents of the Portuguese New School, and gave form to the movement's ideas and representations of teachers' education. The collection, published in Brazil between 1931 and 1950 by the "Companhia Editora Nacional," an internationally renowned company in the book industry, was directed by Fernando de Azevedo, an exponent of the Brazilian New School Movement. The collection in the "Biblioteca Museu do Ensino Primario" contained a significant number of books by Brazilian authors, as well as Brazilian translations into Portuguese from other languages. In this article, the books in the collection present in the Portuguese library will be analysed, as well as the possible reasons for the collection's presence there and possible circulation networks of the New School canons organised through the mediation of publishers.
