A platform agnostic digital publication format that supports rendered and resizable text, illustrations and graphics, “read to me” features and interactive functionality. The format takes advantage of the alternate renditions feature of the OCF of the EPUB® specification and includes both a ShockWave Flash (SWF) based rendition and a HyperText Markup Language (HTML), Java Script (JS), Cascading Style Sheets (CSS) based implementation. In order to avoid duplicating large components (graphics, audio, etc.), files containing those components are not embedded in the SWF files, but are rather externally referenced by both the SWF and the HTML files. A strict and consistent folder structure and file-naming convention improves efficiency and reduces the potential for error.
