This book highlights the importance of the library and information profession in the face of the knowledge industry. It emphasizes the connection between library and information work and education, envisioning a future of working with digital knowledge and lifelong learning. Despite the shift towards digitalization, libraries must strive to provide equal access to knowledge for all users. This involves adopting knowledge management principles, such as measuring the usage of library holdings, evaluating user satisfaction, and continuously educating librarians. By enhancing librarians' educational competence and promoting users' information literacy, libraries can remove intermediaries between users and information. Additionally, library cooperation in building databases and portals, as well as offering 24-hour services, can contribute to seamless access to information.In response to challenges in scientific information and communication, librarians have embraced strategies such as intensifying interlibrary loan services, coordinating acquisitions with related libraries, and employing simpler bibliographic processing and electronic resources. Thus, libraries have evolved and adapted over time to meet the changing needs of society. In the digital age, librarians play a vital role in managing knowledge, promoting information literacy, and providing access to information in a rapidly evolving technological landscape.
