To discuss the concept of "Information Professional", a study was performed, focusing on the history of professions related to the processing of information, with emphasis on the librarian functions. The study's approach included an analysis of the relationships among such areas as Archivology, Librarianship, Information Science, Documentation and Museology. Finally, to verify whether the concept of Information Professional had, or not, a consensus in the literature about Information Science, a compilation was made, of selected works whose object of study was the Information Professional. The conclusion was that there is no consensus on such concept, and that this subject deserves more studies, as much to preserve the integrity of the professional category, as to assure the recognition of its function by the society.
