Convergent vector of library development

At the beginning of the XXI century, the scientific library was transformed into a modern information institution, one of the leaders of society informatization. Today, libraries consider the introduction of ICT and innovations (tested in other areas) as a strategic direction. For scientific libraries, it is urgent to solve the problem of accelerated transition of research to the digital environment, development of new conceptual foundations of library and information activities (expansion of functions of a scientific library). The formation of the theoretical basis for library development in digital realities can be traced in many scientific works of academics and practitioners of the library and information field. There is a tendency to increase the use of the terms: «digital transformation», «digitalization». «Digitalization» is understood as «digital transformation», the penetration of information and digital technologies (Big Data, Internet of Things, cloud technologies, and so forth) into all processes and spheres of society in order to optimize and automate them, increase productivity, and improve communication with users. Digitalization as a new trend in global social development is considered as part of Ukraine’s policy of full membership in the EU.
