Abstract

An interactive electronic book provides a user access to interactive programming. The interactive programming may include interactive files that are linked to the electronic books using electronic links. The electronic links may be included in the text and graphics data of the electronic book. The interactive files may be located in the same file as the interactive electronic book, or may be located external to the interactive electronic book. External locations include an Internet web site, an electronic book viewer and other external locations. Access to the interactive file may be controlled by an operating program and a security program included with the interactive electronic book. The interactive file may include sample problems and quizzes associated with a college textbook, for example. The interactive files may also include accesses to Internet web sites, and other electronic files to complete purchase orders, answer questionnaires, and to receive other data.
