Abstract

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.

Claims

1. A method, comprising:

receiving, at a computer processor, supplemental content to an electronic book from a plurality of user devices associated with end users having downloaded the electronic book, the supplemental content created separately from the electronic book, the supplemental content from the plurality of user devices representing collective supplemental content;
