The richness and diversity of the collection document&#xa0;significant chapters in the construction and circulation of psychology and educational sciences in the twentieth century, especially in the context of Brazil-Europe relations. This encourages research into the theoretical and practical development of these sciences and documents processes of transnational circulation of ideas and proposals in the fields of psychology and educational sciences. The documents in the collection also enable the identification and analysis of intricate processes of institutionalization and internationalization of educational institutions.
