ABSTRACT
Digital library projects throughout the world have been creating very large-scale repositories of digital information on a wide range of topics. The contents of digital libraries today include collections of scientific data, digitized versions of classical and modern texts in the original languages, commentaries on those texts, historical and current social science survey information, collections of digitized video and audio, and collections of images-including digitized paintings, sculpture, drawings, and other museum objects. In short, the cultural heritage of the world is rapidly being replicated in digital form.
