This paper explores the key concepts of metaverse, metaliteracy and digital libraries and analyzes their importance, opportunities and challenges in the contemporary digital environment. Metaverse, as a virtual space for interaction and creation, is increasingly becoming the center of digital activities, opening up new opportunities for interaction, collaboration and content creation. On the other hand, metaliteracy becomes a key skill for successfully navigating the digital world, highlighting the need for critical thinking, information evaluation and responsible behavior in the online environment. Digital libraries play an important role in this context, providing access to a wealth of digital resources, tools and content. They become centers of education, research and creativity, adapting to new technological trends and user needs. However, with progress come challenges, including privacy, copyright and data security issues, which require careful management and innovative strategies. Through the integration of the metaverse, the development of metaliteracy and the evolution of digital libraries, we are creating the foundations for a more inclusive, informed and engaged society in the digital era. All these elements are key to shaping the positive benefits of digital transformation in the global digital realm.
