Medium containing information gathered from material including a source and interface for graphically displaying the information

摘要

An electronic medium is a new form of publication for a source material, such as a book. The medium includes information about features of the source material and features of secondary information related to the source material. The medium can be used with a visualization system. With the system, a user is provided with tools that respond to the user's needs and requests at a level of the collection, rather than just with a single work.
