Comprising more than 9 million items that document U.S. history and culture, the site is organized into more than 100 thematic collections based on their original format, their subject matter, or who first created, assembled, or donated them to the Library. LC's Digital Collections provides free and open access to manuscripts, prints, photographs, posters, maps, sound recordings, motion pictures, books, pamphlets, and sheet music. It is a digital record of American history and creativity. Collections may be browsed individually, searched individually (including full-text searching for many written items), or searched across multiple collections.
