I also work on long, non-fiction books in the .indb format. I am very disappointed that the endnotes feature in Indesign does not support back-of-the-book endnotes. Please fix! I see colleagues have been asking for this for several years. Move it up the queue!

Please implement this feature as soon as possible. It is critical for long, non-fiction texts.

Has Adobe or InDesign responded on this topic? It's a must that endnotes be consolidated at the end of the book, not after each chapter when using the book feature.

such an endnotes should also include the section titles of the individual documents. this is important too.

Endnotes are possible, and an index, but only in one InDesign (.indd) document at a time. As of Nov, 2020, InDesign has a basic endnote function, but it seems to only work in one distinct .indd document at a time, not in the book file (.indb) function. I haven't tried to merge two .indd docs with endnotes or with indexes. Will that work without script? Thus, Adobe offers, paradoxically, a book file (.indb) that doesn't work for a huge number of books, like non-fiction books that need indexes and endnotes at the end. And as another commentator noted, the Adobe User Manual doesn't point this out, which by being honest would save the users a lot of time, but they make us look it up and read these comments. The book file (.indd) only consolidates page numbers and the TOC from the various chapter docs, not the index or the endnotes! I'm going to put my 200-page to 500-page books each into one .indd document, and not use a .indb book file. The other comments are spot on: How is the supposed industry standard publishing product any good for non-fiction books without endnotes on an index at the end? Again, both of which aren't possible in InDesign's so-called "book" file .indb. Adobe, please think of the non-fiction book market (both EPUB and print), would you? While Adobe keeps adding to its thousand ways to adjust the how the letter A looks on the book cover (which we all love, to be sure), Adobe ignores these these very basic functions for book publishers (indexing, combining documents, endnotes) which would bring customers running from the many, many people who are working on books and long documents. Also, be warned users, the book file (.indb) can eliminate your hyperlinks in some cases, so you have to manually reenter them, see https://www.bookdesignmadesimple.com/indesign-book-feature/

We need endnotes at the end of a book.

Yes. This feature is a must for book publishers like myself. Please add it.

Full agreement. Still a pain in the butt issue.

The endnotes must be in the end of book, not in the end of each book document! It's urgent!

Still no solution to this huge problem??? HAs anyone figured out how to get around the flaw in InDesign, or how do you all deal with this problem?
Desperate for a solution!!

Like Jannette, I'm flabbergasted that InDesign can't do back-of-book endnotes. And like another reader commented, it's like building a car without a transmission! If you can't fix the issue, at least fix your user manual to make it clear that back-of-book (vs. back-of-document) endnotes are impossible. But it's really unacceptable that supposedly sophisticated software can't do a basic publishing task.

I can't believe that this has not been resolved yet. What publishing software wouldn't have this ability?

I know this post is rather old now, but I agree with much of what you have said. However from what I can make out, one of your issues can be fixed in the current 2018 version. In the Type menu there is a Document Endnotes Options section. In the following dialogue box there is a dropdown button that allows you to change numbering from continuous to per story.

PLEASE add these features to the footnote and endnote functionality of InDesign:
- Continuous numbering of footnotes and endnotes throughout the various indd files within a book document
- Ability to put the endnotes of the different indd files within a book document in a separate .indd file at the end of the book; numbering continuous OR per chapter.

Please, please, PLEASE implement this desperately needed feature. Thanks!

A great feature. It would be very helpful indeed. Thanks in advance.

Endnotes for books so that all references can be included en masse in a separate chapter at the end.. This would be EXTREMELY helpful. Thanks!
