Responsabilidades sociales y políticas de los bibliotecarios = Social and political responsibilities of librarians

Presentation (which title is: "Social and Political Responsibilities of Librarians") given to the students and professors, lecturers, readers and faculty body of the College of Library and Information Science (LIS) of the School of Philosophy and Letters at the Autonomous University of Nuevo Leon, Mexico, thanks to the invitation of Mrs. Maria del Rosario Banda Martínez, lecturer and MLS of that program (to whom the author is very thankful for such invitation). The presentation covered around these 5 themes which appear to librarians as ethical problems on the political and social scenarios where such reality expects that they assume their consequent responsibilities: 1)Social problems, 2) Lack of a social and political compromise, 3) causes of the lack of social and political compromise, 4) social and political challenges, 5) recommendations to librarians. It is noteworthy the remark that librarians should adopt ethical principles based on the reality, the materiality, and physical nature where libraries and users exist. They should embrace a critical, analitical, eskeptical and secular thought above all of their possible religious, mythological, or fantastical dogmatisms or of any other kind they may have as personal beliefs
