Library of Congress -- World Digital LibraryLaunched in 2009, the World Digital Library was a project of the U.S. Library of Congress, with the support of UNESCO, and contributions from libraries, archives, museums, educational institutions, and international organizations around the world. The WDL sought to preserve and share some of the world’s most important cultural objects, increasing access to cultural treasures and significant historical documents to enable discovery, scholarship, and use. Books, manuscripts, maps, and other primary materials in the WDL collection are presented in their original languages; more than 100 languages are represented, including many lesser known and endangered languages.
