These cultural treasures include, but are not limited to, manuscripts, maps, rare books, musical scores, recordings, films, prints, photographs, and architectural drawings." The site was developed by "the U.S. Library of Congress, with contributions by partner institutions in many countries; the support of the United Nations Education, Scientific, and Cultural Organization (UNESCO); and the financial support of a number of companies and private foundations." After selecting a region the user is able to narrow the documents by time period, country, topic, type of item, or institution. Ease of use encourages exploration.
