How to Solve EPUB Problems on Nook & Kobo

8ballby the Boom-Books Production Team

21st-century e-book publishing is full of questions and mysteries. Some are opportunities which can become chores. For instance: back matter: that strange, ancient substance which often goes unnoticed even though it fills big chunks of the universe. Traditionally, back matter follows a book’s text and comprises anything from footnotes and index to Full Copyright Notice and About the Author. It’s a great place to tell readers about other books by the same author, publisher, or both. In an e-book, it’s a chance (and therefore an obligation) to include links to those books, and other clickable gateways for curious readers.

At Boom-Books we frequently update the links in our back matter. Lately, as the EPUB format has become more universal (that’s its purpose), paradoxically we’ve run into new glitches. Sometimes the robots-in-charge reject a book that’s been published in this same venue, in this same format, for years–with no explanation but a cryptic declaration which recalls the advice from a Magic 8-Ball:  Reply hazy. Try again. Or simply: No.

Recently we’ve had responses from Nook and Kindle to their EPUB format glitches which may be helpful to others facing the same problem.

On Kobo, our revision (repeatedly) provoked “unable to upload this e-book as expected.” Here’s Kobo’s Support’s response:

We’ve had a small number of authors report this issue to us. Our web team are currently working on a fix but in the meantime, we’ve found a work around.

Would you be able to clear the all content and submit the content file again?
1. Click the ‘Clear all’ button and to remove the content you had previously uploaded.
2. Click ‘Stop editing’
3. Go back to the ‘Add eBook Content’ section
4. Upload the saved content file and click ‘Replace File’.
5. Click ‘Next’ to save your changes.
6. Click “republish” button.

This should allow you to publish your edited file without running into any other errors.

On Nook, the formerly outstanding Previewer for uploaded e-books has evidently been replaced by a Manuscript Editor, which in our case introduced format errors to a previously successful EPUB file.

Here’s Nook Support’s response:

If you are not satisfied with the way your .epub manuscript file was imported into the Manuscript Editor or displays in the Previewer, you can instead put your .epub file on sale as a NOOK Book exactly as it was created by you.

After you submit all of the required NOOK Book details, a “Publish” button will appear in the upper right corner of the Manuscript page. Click this “Publish” button and select to put on sale “The original .epub file I uploaded”.

The “Preview NOOK Book” link displays the contents of the Manuscript Editor, so if you select to put On Sale “The original .epub I uploaded” then you can skip this preview because you are not putting the contents of the Manuscript Editor On Sale.

Once your Project is on sale as a NOOK Book, you can click “Download ePub” on the Manuscript page to view the NOOK Book file that customers download after making a purchase.

We’re committed to keeping as many book-publishing outlets open as possible. We hope this will help.
