Methodological Principles for Adapting of Performance Indexes of Classical Libraries for a Comprehensive Assessment of Electronic Library Systems in Vocational Education

The purpose of the study is to identify key methodological principles for adapting of performance indexes of classical libraries to assess the pedagogical and educational effectiveness of electronic library systems in professional education, as well as to determine their practical significance for the formation of tools for analyzing the impact of digital resources on the learning process. Materials and methods. The study used an integrated approach combining theoretical analysis and empirical methods. A systemfunctional approach was applied to formulate the advantages of electronic library systems (remote, fast, equal, easy ... access), which provided a comprehensive analysis of their impact on the educational process. The historical and analytical method was used to identify key performance indexes used in evaluating the activities of classical libraries, which made it possible to justify their adaptation to the conditions of the digital educational environment. The empirical analysis included the processing of statistical data provided by electronic library systems using information from administrative offices and open sources. The regulatory and legal analysis covered the study of state standards and the provisions of Federal Law No. 273-Federal Law “On Education in the Russian Federation”, which ensured the verification of the compliance of the electronic library systems’ functionality with established educational requirements. The comparative method was applied to compare traditional library performance indexes with new metrics determined by the specifics of the digital environment. The results of the study demonstrate that despite the continuity of the main performance indexes from classical libraries, they are transformed and acquire a new quality in the digital environment. Metrics such as the number of registrations, the number of visits and requests, the number of bookings, bounce statistics, and search queries are becoming more detailed thanks to digital technologies. The adapted indexes allow for a more detailed approach to assessing the pedagogical and educational effectiveness of electronic library systems – the impact on the formation of professional competencies, support for learning continuity, and achievement of the federal state educational standard of higher education. The conclusion emphasizes that the results obtained create a theoretical and methodological basis for the development of a comprehensive model for evaluating the effectiveness of electronic library systems, requiring further verification and in-depth study of the relationship between the use of electronic resources, students’ academic performance and the formation of professional competencies.
