Librarian of Congress James H. Billington and UNESCO Assistant Director for Communication and Information Abdul Waheed Khan recently signed an agreement at UNESCO headquarters in Paris pledging cooperative efforts to build a World Digital Library web site. The World Digital Library will digitize unique and rare materials from libraries around the world, including manuscripts, maps, books, musical scores, sound recordings, films, prints, and photographs, and make them available for free on the Internet. The objectives of the World Digital Library include promoting international and intercultural understanding; increasing the quantity and diversity of cultural materials on the Internet; and contributing to education and scholarship.
