The article analyzes the positive foreign experience of implementing augmented reality (AR) library projects. It has been found out that the most common uses of augmented reality in libraries today are providing access to information products with augmented reality and their promotion, navigation of library space and resources, promoting user education through the creation of appropriate applications with learning materials and resources and simplification for the user assimilation of information due to the diversity and interactivity of its visual presentation, informing and providing access to cultural heritage sites, organizing tours and exhibitions. Given that the use of AR in libraries not only expands the range of services and resources but also positively affects its reputation as an interactive creative institution, open to users and innovation, AR technology is effective not only in the library service system but also in the marketing activities of the institution, helping to attract new users. Current approaches to the implementation of library projects using augmented reality technology are highlighted. Their assistance in strengthening corporate culture, inter-institutional ties, and civil society is substantiated. It has been proved that the AR applications created as a result of project implementation operate on the principle of integrated information products, which allow the user to access distributed information from one access point via mobile phone, integrating not only information of the virtual space of the Internet environment but also real, physical, space. The advantages of AR implementation in the library have been determined, among which: budget realization, easy integration with available technologies, and promotion of interactivity of library service. The need for professional development of librarians and the organization of training courses on the use of immersive technologies in library activities is emphasized.
