 The results. It has been established that Argentina was the first among Latin American countries to establish a training school for librarians in the structure of the Philosophy and Literature Faculty of the University of Buenos Aires back in 1922.

The system of post-graduate library education began to take shape in the 1970s, when in 1972 the first post-graduate program in the field of “Library and Information Science” was opened in Brazil at the School of Communication and Arts of the University of São Paulo, and in 1980 — the doctoral program as well. Currently, in the countries of Latin America, only the leading metropolitan universities have educational programs of master’s and Doctoral levels.
