World Digital Library (WDL)
The World Digital Library (WDL) is a project of the U.S. Library of Congress, carried out with the support of the United Nations Educational, Cultural and Scientific Organization (UNESCO), and in cooperation with libraries, archives, museums, educational institutions, and international organizations from around the world.
The WDL makes available on the Internet, free of charge and in multilingual format, significant primary materials from all countries and cultures.
WDL items can be browsed by place, time, topic, type of item, language, and contributing institution. The search feature can be used to search all of the metadata and descriptions and the full text of printed books on the site.
Each item on the WDL is accompanied by an item-level description that explains its significance and historical context. Additional information about selected items is provided by curator videos. Other features include advanced image-viewing, timelines, interactive maps, and in-depth thematic sections on selected topics (in preparation).
All navigation tools, bibliographic information (also known as metadata), and content descriptions are provided in seven languages: Arabic, Chinese, English, French, Portuguese, Russian, and Spanish. Metadata and descriptions can be listened to on a text-to-voice conversion option that is available for every item in all seven interface languages.
Books, manuscripts, maps, and other primary materials on the site are not translated but presented in their original languages. More than 100 languages are represented on the WDL, including many lesser known and endangered languages.
