摘要:The aim of this article is to discuss the constituent aspects of Information Science taking two parameters into account: the informational thought, that identifies the solution given at different historical moments to the questions concerning the access and the use of registered contents, and the extension of the change of modern to post-modern science, when the name of the discipline was coined almost at the same moment as the attribution of traces that resulted in the field’s lack of identity. A conceptual synthesis of modern and post-modern science is presented, supporting the recognition of the informational thought of Naudé, Dewey, Otlet and Sola Price. The rescue of ideas showed fruitful, allowing us to recognize important interventions in the area that evidence the dynamics of information, limited by the mechanical reading carried out for years. Meanwhile, it suggests that the concept of disciplinary integration is more appropriate to provide the development of the field.
