The main functions of a national library are to collect, preserve, and provide access to the cultural and intellectual heritage of a country. National libraries typically have a broad and comprehensive collection that includes a wide range of materials, such as books, manuscripts, photographs, maps, and other types of media. They may also have rare and unique materials, such as manuscripts, incunabula (books printed before 1501), and maps.
In addition to their collections, national libraries also often have a mandate to preserve the cultural heritage of their countries. This may involve preserving physical materials, such as books and manuscripts, as well as digitizing materials so that they can be accessed electronically.
National libraries also often have a strong focus on education and public outreach. They may offer educational programs, public lectures, and other events to promote knowledge and learning. They may also have exhibitions and other public displays of their collections.
In addition to these functions, national libraries may also have a variety of other responsibilities, depending on the specific goals and mandates of the library. For example, they may be involved in research projects, support the work of scholars and researchers, or collaborate with other cultural institutions and libraries.
