Dear Notjohn,
Thanks so much for mentioning citations, which are essential for references in academic articles.
In my many thousands of pages website, informationphilosopher.com, I wrote a javascript to "Cite this page," but of course a web page is the equivalent of many print pages, so it's very rough. Maybe I should add sub-page numbers! Many scholars have used it and thanked me for an automatic citation. My site is widely used in schools. Google Analytics reports 700-800 unique new visitors a day.
By the way, the original material for my two books (so far) and maybe seven more books to come, is now on my website. I also post there free PDF versions of my first two books.

And you can read more about my revisionary history of Einstein and quantum mechanics here.

Coming back to real page numbers, my colleague Heather Hedden ran a subgroup of the American Society of Indexers on web indexing years ago. That has now been renamed digital publishing indexing, and she is preparing a report for the next annual meeting of the ASI on indexing a digital publication.
I hope to help her with research on the current state of the art. And we might submit an article to InDesign Magazine on the subject.
Frankly, all the standard EPUB readers do an excellent job (especially with InDesign index output) so Amazon is now a travesty that would be great to repair if we can find a template for an EPUB FXL sample file that converts both ToC and index with working hyperlinked page numbers.
For my purposes, Kindle reflowable is quite acceptable now - with my Indesign EPUB3 reflowable converted by Kovid Goyal's Calibre (although I have read many comments saying this does not work) and my unorthodox insertion of a paragraph with the page number at or near a page break.
Thanks again,
Bob
