This is a custom, proprietary package format used exclusively by the Watch Tower Bible and Tract Society. While it contains the same foundational building blocks as an EPUB (text, structural data, and images), it is bundled with a specialized SQLite database. This database holds unique app-specific data, such as multimedia links, study notes, highlighting capabilities, and verse cross-references designed to sync perfectly with the JW Library app interface.
