Emphasis is placed on the role of scientific and technical libraries in the education of Soviet workers. One of the main tasks of technical libraries is to educate workers to respect their professions, and to maintain communistic attitudes towards labor. Librarians acquaint younger workers with literature on the history of their plants with booklets about the plants' best people, innovators' achievements, advanced experience, etc. Book propagandists as a rule know the names and working places of all their subscribers, their readers' interests and attitudes toward work and literature regarding their interests and demands, social obligations, education and family status. The rate of production, growth of the professional level of engineers, technicians and workers, and use of the achievements of science and engineering depend to a great extent on the output of the industrial workers.
