Public libraries also provide books and other materials for children. These items are often housed in a special section known as a children's library and attended to by a specialized children's librarian. Child oriented websites with on-line educational games and programs specifically designed for younger library users are becoming increasingly popular. Services may be provided for other groups, such as large print or Braille materials, Books on tape, young adult literature and other materials for teenagers, or materials in other than the national language (in foreign languages).
