Launched in 2009, the World Digital Library (WDL) 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and share some of the world’s most important cultural objects, increasing access to cultural treasures and significant historical documents to enable discovery, scholarship, and use.
