Edit EPUB metadata from a single source card that lists the title, author, language, publication date, series name, and volume number. Without that card, a small series-name difference or a copied volume number can survive into the package.
This article edits one existing book. Creating a new second volume from a shared series template is the subject of the companion creation guide.
Capture the current values first
Create before-and-after columns. Mark unchanged fields as “keep” instead of leaving them blank. For a second volume, the plan might keep title and author formatting, normalize the series name, and set the numeric volume field to 2.
Do not mix the display phrase “Volume 2” with a field that expects only the number 2. Keep a subtitle out of the shared series-name field.
Make one controlled edit
- Record the current metadata.
- Confirm the canonical series spelling.
- Enter volume number 2 in the test copy.
- Verify that unchanged fields stayed unchanged.
- Export and inspect the package metadata.
Rune Studio can set bibliographic and series information for EPUB output. The completed test used volume number 0, the single-volume setting. It is not evidence of a successful volume-two metadata edit, so the example above remains a required test rather than a claimed result.
Recover field by field
If the title changes unexpectedly, restore only the title and keep the intentional series correction. If the volume disappears, inspect the numeric field and display text separately. Finish one book before applying the change to the rest of the series.
Repeat the smallest proof on another day
Before adopting the volume-two metadata edit, close the project and repeat the smallest useful path later. Record before and after values, unchanged fields, series spelling, and numeric volume value. A result that depends on memory or an already-open preview is not yet a dependable routine.
Keep one untouched copy and change a single condition per retry. If the second run differs, identify whether the source, operation, or inspection changed before expanding the scope. This rehearsal is also the point to keep a volume-two success inferred from volume zero clearly labeled as unverified rather than filling the gap with an assumption.
The next practical step for the volume-two metadata edit is to prepare the smallest useful copy and write down its expected result before touching the production manuscript. Extend this particular workflow only after the observed result matches.
Conclusion
One source card makes metadata editing auditable because it separates changes from values that must remain. Testing completed so far verifies the single-volume setting, not volume two. Test 2 on a short project and inspect the generated metadata before editing the production EPUB. Review Rune Studio’s EPUB metadata tools
