EPUB – Endnote backlink issues for INDB files
When exporting EPUB 3.0 (and 2.01) from an InDesign(2022, version 17.4) book file, endnotes only link in the first chapter where they are found. Subsequent chapters reveal <a> tags with empty href attributes.
Backlinks are required by virtually all ebook publishers. For academic books, endnotes are essential and the request for EPUB formats is only increasing.
So far Adobe Car's response: "Currently, we do not have a workaround for this issue other than creating a single document instead of book or manually modifying backlink in the exported EPUB file." This isn't acceptable or even always possible.
Fix for this issue is now available in the latest release of InDesign 2023 - that is, InDesign 18.1 version.
Please update to this version of InDesign to get the fix.
