Abstract: Y0989-014 A method for creating online information from the same marked-up source material used to create printed information such as a word processor or a mark-up language source use with a text formatter. A book data stream is provided, in a new intermediate format for storing online information, specifically designed to be used by a book display program. This data stream captures and preserves structural information about books. It is uniquely suited to display online books in a very usable manner on a variety of display devices. Also provided is a new kind of program, (a book display program) for manipulating the book data stream, and allowing users to interact with the online information. A distinguishing characteristic of the book display program is its use of the metaphor of a hard copy book on the display screen. It lets readers treat online books like hard copy books. This program uses the book data stream (described above) as its input.
