Managing Calibre Series & EPUB Metadata on iOS: The Complete Guide
How to fix series ordering, repair corrupted OPF packages, and organize multi-book sagas on iPhone & iPad.
Multi-book series often get scrambled in Apple Books and e-reader libraries because their EPUB OPF files lack proper series tags or contain mismatched Dublin Core titles. EpubTidy provides a touch-first interface to manage Calibre series conventions (calibre:series and calibre:series_index) and EPUB 3 collection elements directly on iOS, ensuring your book series display in perfect chronological order.
Essential Facts & Reader Takeaways
- ✓Fix disorganized libraries: assign series names and decimal volume indexes (e.g., Book 1.5, Book 2) directly from iPhone or iPad.
- ✓Dual Standard Support: writes both legacy Calibre OPF meta tags and modern W3C EPUB 3 collection elements for universal compatibility.
- ✓Instant Dublin Core Correction: fix corrupted author sorts, missing publication dates, ISBN identifiers, and book blurbs.
- ✓Automatic Apple Books Hierarchy: Apple Books natively honors EpubTidy's series tagging to group sagas into neat, ordered stacks.
- ✓No XML or regex knowledge needed: point-and-tap interface eliminates the risk of corrupting EPUB package archives.
Why Book Series Get Scrambled in Digital Libraries
The underlying metadata disconnect
Anyone who reads sprawling fantasy, romance, or sci-fi sagas knows the frustration of importing a five-book series into an e-reader only to find the books sorted alphabetically by title rather than by narrative chronology. Book 4 appears before Book 1, spin-off novellas break the sequence, and cover art styles clash.
This occurs because standard Dublin Core metadata (the `dc:title` and `dc:creator` tags created 20 years ago) had no native concept of book series. Calibre solved this by introducing custom XML tags like `<meta name='calibre:series' content='The Stormlight Archive'/>` and `<meta name='calibre:series_index' content='1'/>`.
Until now, injecting these tags into an EPUB required desktop software. If you downloaded a book while on vacation or away from your desk, your library remained in disarray.
Effortless Series Tagging on iPhone & iPad
A visual workflow designed for series enthusiasts
EpubTidy introduces a dedicated Series Management card within its metadata editor. When you open a book, simply enter the series title and designate its volume number. EpubTidy supports both whole integers and decimal fractions (such as 2.5 for companion novellas).
Under the hood, EpubTidy writes both the Calibre meta tags and the modern EPUB 3 `<meta property='belongs-to-collection'>` elements. When you send the repaired book to Apple Books or your favorite mobile reader, the application immediately recognizes the series stack and presents the books in pristine reading order.
Repairing Broken Tables of Contents and OPF Spines
Recovering unreadable or misbehaving books
Beyond series metadata, EpubTidy inspects the internal spine and Table of Contents (both legacy `toc.ncx` and modern `nav.xhtml`). If a book has missing chapter links, non-functional bookmarks, or corrupted manifest entries that cause e-readers to crash, EpubTidy's repair engine reconstructs the navigation tree so you can jump smoothly between chapters.
