The purpose of the article is to identify ways to develop the system of scientific and methodological support for the work of structural divisions of scientific institutions of the Ural Branch of the Russian Academy of Sciences (UB RAS) (libraries, departments, sectors) that provide information and library support for their activities. The scientific and methodological center for libraries of scientific institutions of UB RAS is the Central Scientific Library of the Ural Branch of the Russian Academy of Sciences (CSL UB RAS). To determine the priority directions of development of CSL UB RAS in the fi of scientific and methodological support of the network libraries, the analysis of the main indicators of their activities in the period from 2017 to 2021 was carried out. It revealed a steady decline in the indicators of library visits in stationary conditions, a decrease in the receipt of literature on physical media, an increase in the issuance of documents (mainly electronic documents from remote full–text databases) and an increase in applications in the distant format. Based on the data obtained and taking into account current trends in the fi of information support for science, the priority directions of CSL UB RAS activities developing the scientific and methodological support system for network libraries have been formulated. The implementation of these directions will ensure the effective use of the aggregated collection of libraries’ printed publications, the joint development of electronic sources of foreign scientific information, the organization of effective information services using remote technologies, the development of scientific libraries’ personnel potential, taking into account current trends in the information infrastructure of science. Strengthening system links within the network of libraries of UB RAS scientific institutions will become one of the components for building an effective system of cooperation and coordination of libraries of the Russian Academy of Sciences.
