IdunnBacklist · Offline EPUB author-page updater 1.0.0 · Chrome on Linux
Keep your author page current across your backlist.
Use one catalog and biography to replace an existing standalone author page in supported EPUB 3 books. Review every replacement, then export new copies with the right link column for each edition.
Use this when each book already has a separate author/catalog page and you want reviewed replacements from one shared catalog. Selecting a page replaces all its contents. A page combined with your final chapter must be split in your authoring tool first.

Inspect the practice books and their replacements
Includes the original books and six actual sample editions with reports. The application for updating your own books is in the paid download. Example.com links are placeholders.
- Choose each replacement: Read the original page and approve every book/edition preview.
- Reuse a shared catalog: Select up to three URL columns and omit the current book from its own list.
- Keep originals and a record: Download new EPUB copies, preservation reports and a project containing settings and hashes.
What it helps you do
For independent authors updating a biography, book list or destination links across finished books. Explicitly select the page and catalog identity for each book. Each generated list excludes the current title. The entire selected page is replaced, so it must be separate from prose you want to keep.

A practical example
Mira Fen: three books become six reviewed editions
Start with
Three fictional original EPUBs, one shared catalog and biography, and two selected URL columns: Amazon and Neutral.
Get this result
Six EPUB copies plus HTML/JSON reports. Lantern Harbor lists The Brass Tide and Winter Signal, omits itself and includes the shared biography. Chapters and navigation retain their decompressed bytes. The selected XHTML page changes, and the package modification timestamp changes; overall ZIP bytes need not match.
Examples use fictional or synthetic data. Follow this example step by step.
