The emergence of the Internet and the wide availability of affordable computing equipment have created tremendous interest in digital libraries and electronic publishing. This book is the first to provide an integrated overview of the field, including a historical perspective, the state of the art, and current research. The term "digital libraries" covers the creation and distribution of all types of information over networks, ranging from converted historical materials to kinds of information that have no analogues in the physical world.
