Library and Information Science (LIS) is an interdisciplinary field focused on the creation, organization, management, communication, and use of recorded information in all its formats. It educates professionals like librarians and archivists to organize and provide access to information, serving as custodians of knowledge in libraries and other institutions. The field combines traditional library science with information science, incorporating new technologies, and professionals work to design information systems, preserve history, and connect people with needed resources.
