CONTENT-BASED NAVIGATION FOR ELECTRONIC DEVICES

摘要

Content-based navigation of an electronic device includes receiving supplemental content to an electronic book. The supplemental content is created separately from the electronic book. The content-based navigation also includes associating an identifier of the electronic book with the supplemental content, storing the supplemental content with the identifier in a storage device, and creating an index to the supplemental content that is searchable by the identifier of the electronic book. The content-based navigation further includes providing end user devices with access to the supplemental content in the storage device via the index.
