  • Patent number: 5142662
    Abstract: An electronic publishing system stores interrelated illustrations and items of text data, establishes data linking such items of text data to correlated locations in the illustrations, and stores such linking data in the recording part of the system. Records of interrelated illustrations and items of text data fixed in tangible media for reproduction by user-operated electronic equipment may be produced in this manner. One of the stored illustrations may thus be retrieved, and a display may be provided of that retrieved illustration. The user then selects a desired location in the displayed illustration, and the electronic equipment employs the stored linking data for retrieving any stored item of data correlated to the desired location in the displayed illustration. The item of text data thus retrieved may be displayed, preferably in conjunction with the illustration to which it pertains. Data linkage may also be between illustration and interrelated illustration.
