The Digital Public Library of America (DPLA) contains metadata records —information describing an item —for millions of photographs, manuscripts, books, sounds, moving images, and more from libraries, archives, and museums around the United States. Each record links to the original object on the content provider’s website. The DPLA brings together the riches of America’s libraries, archives, and museums, and makes them freely available to the world. It strives to contain the full breadth of human expression, from the written word, to works of art and culture, to records of America’s heritage, to the efforts and data of science. The DPLA aims to expand this crucial realm of openly available materials, and make those riches more easily discovered and more widely usable and used.
