Way to tell which books have reference pages in advance?

[mallomar]

Hi –

just finished reading William Gibson's Neuromancer. I switched between my Android phone, my small Boox and my large Boox depending on where I was reading and found the reference pages very helpful, because sometimes even with progress sync it took me to the wrong page due to the very different screen size of each device.

I went to read the sequel, Count Zero, but I noticed there are no reference pages in the epub. I googled and saw it's something built into the file itself. I found some others but none have reference pages when I load them in KOReader. I'm hoping there's a way to figure out which ones have reference pages by looking at the source code of the book in Calibre rather than having to first send the file to KOReader and then check.

TL;DR: Look for <pageList> tags, particularly in the toc.ncx (not sure if that's always the case, though).

Btw, doesn't progress sync work with read percentages, rather than page numbers (particularly for reflowable documents)?

Thanks, I found it under the nav.html file in the EPUB (though, strangely, don't see where it is in the AZW3 I converted from):

<nav epub:type="page-list">
			<h1>Print Page List</h1>
			<ol>
				<li><a href="xhtml/08_Part_1_Chiba_City_Blu.xhtml#page_1">1</a></li>
				<li><a href="xhtml/08_Part_1_Chiba_City_Blu.xhtml#page_2">2</a></li>
				<li><a href="xhtml/08_Part_1_Chiba_City_Blu.xhtml#page_3">3</a></li>
				<li><a href="xhtml/09_One.xhtml#page_4">4</a></li>
				<li><a href="xhtml/09_One.xhtml#page_5">5</a></li>
				<li><a href="xhtml/09_One.xhtml#page_6">6</a></li>

Yes, but my Book Note Air 2 has a 10.3" screen, my Android phone has a 6.4" screen and my Boox Nova Air C has a 7.8" screen, so it doesn't always bring me to the right page in progress sync, since one page on the larger screen can cover several on the smaller ones.

ֵֵEDIT: Are page indexes with page numbers rare? I downloaded many versions and the only one I found which page numbers is in Portuguese and it actually does it differently, with pages in a page-map.xml:

<?xml version='1.0' encoding='utf-8'?>
<page-map xmlns="http://www.idpf.org/2007/opf">
  <page href="OEBPS/Text/Cover.xhtml" name="1"/>
  <page href="OEBPS/Text/Cover.xhtml#GBS.0001.01" name="2"/>
  <page href="OEBPS/Text/Cover.xhtml#GBS.PT2" name="3"/>
  <page href="OEBPS/Text/Cover.xhtml#GBS.0002.01" name="4"/>
  <page href="OEBPS/Text/Cover.xhtml#GBS.0002.02" name="5"/>
  <page href="OEBPS/Text/Entrada.xhtml" name="6"/>
  <page href="OEBPS/Text/TOC.xhtml" name="7"/>
  <page href="OEBPS/Text/Ded.html" name="8"/>
  <page href="OEBPS/Text/Interrup.html" name="9"/>
  <page href="OEBPS/Text/c1.html" name="10"/>
  <page href="OEBPS/Text/c1.html#GBS.0014.05" name="11"/>
  <page href="OEBPS/Text/c1.html#GBS.0015.04" name="12"/>
  <page href="OEBPS/Text/c1.html#GBS.0016.04" name="13"/>

Perhaps this user patch can help you calculate your own.
I don't use it myself, but I've learned about it because I had to support it for KOHighlights..

Thank you, I'll look into this. I actually caved and bought the book because I had a $3 Amazon credit, so it ended up being just 99¢. As much as I don't want to give Amazon more business after them disabling download and transfer for Kindle books and because I also own the book (a 2012 copy, that isn't on Amazon any more), I really wanted one with page numbers and this one is advertised:

Contains real page numbers based on the print edition (ISBN 0441117732).

However, there is nothing with page-list or page-map in the book files and nothing shows on KOReader, so Amazon must be encoding it differently, which is a bummer.

EDIT:Used credit I also had with Google to buy it through Google Books and the page numbers show. Good to know when deciding between buying an EPUB or through Amazon, especially given that Amazon is disabling downloading in ten-days.

EDIT 2:Pulling the KFX off of my Kindle and converting that to EPUB, the file has a page-map.xml. I guess that's one benefit of Amazon blocking download and transfer.
