Library science is the study of how to manage and organize information resources in libraries. It involves understanding how to classify, catalog, and preserve books, digital media, and other materials. Library scientists also focus on providing access to information and helping users find the resources they need. In addition to managing collections, library science includes the study of information technology and user services. Professionals in this field, often called librarians, work to create programs that promote literacy and learning. They also engage in research to improve library services and adapt to the changing needs of their communities.
