This article aims to explore the impact of the library environment on the quality of STEM (science, technology, engineering, mathematics) education and to propose methodological foundations for the effective use of resources. The study analyzes the transformation of the modern library’s traditional role, emphasizing its potential not only as a repository of information resources but also as an interactive learning and research space. The relevance of the research lies in the need to fully utilize the potential of library resources to enhance STEM education. By applying literature review, analytical, and systematization methods, the authors suggest ways to effectively integrate the library environment into the educational process. The findings reveal that the effectiveness of an educational environment built on the basis of the Resource-Methodological System (RMS) depends on the harmonious interaction of its four main components: resources, research opportunities, methodological support, and socio-cultural environment. The article proposes methodological mechanisms for developing students’ practical skills, research competence, and professional socialization through the use of library resources.
