Fractional Page Numbering

There are already quite a few numbering schemes for showing location in an ebook, but I would like to discuss one more, (decimal) fractional page numbers. This would allow "real page numbers" that match a specific print version for reference purposes (but does have the problem that many books have multiple print editions with varying pagination), and still show change for each ebook page turn.

I did some experimenting and it can already work on some EPUB and Kindle readers (example screen shots attached).

I started with the plain text for Henry Ford's autobiography My Life and Work and added asciidoc formatting markup. Next page number link targets were added based on a scan at archive.org, and when that was working, half-page link targets were inserted between each pair of "real page numbers".

Also attached EPUB, KF8 (azw3), and KF7 (mobi) formats and Kindle apnx files to the next post. The uncompressed mobi8 apnx file needs to be copied to the .sdr folder the kindle creates for the book and the mobi7 apnx needs to be copied to the same place as the book. The EPUB uses the page-map method for page numbers (none of my readers support pagelist numbering), but it would be easy to make a pagelist version.

The devices I tested that supported the fractional page numbering were Pocketbook 360, K4NT, PW3, Voyage, Oasis 2, and Onyx Boox M92.

It did not work on original Kobo H2O with original firmware, koreader on Voyage, or Calibre.

The asciidoc and other support files will be attached to the second post.

Fadedpage on some books puts a floating at right margin in a box faint real page number (of edition used) using cunning CSS. Dr Dolittle some titles? and C.S. Lewis 'Till We Have Faces'
I figured out the regex to bulk delete it.

Note that many Fadedpage books are only out of copyright in countries that are +50 or didn't retrospectively implement +75. Not PD in USA.

If you want real page numbers, that works. No need for fractions.

Page numbering is like Trump, Brexit or Nationalists/Republicans vs Unionists in N.I. There are two camps on eBooks and I doubt any scheme will convince those that want "real page numbers" or that point out that only a percentage progress works on ebooks (unlike PDFs).

Interesting idea. The giant thread illustrates the two camps thesis.

I am curious, what is the purpose of fractional page numbers?

I understand the start point of each numbered page being marked in the content.

Some people like for the position in book to update with each screen and never really got all that comfortable with amazon location numbers, even after 10 years. In the great page numbering debates, % often gets touted as a solution, but integer % updates slower than "real page numbers" for books longer than around 150 print pages. The intent of fractional page numbers is to give frequent updates while preserving compatibility with "a" print edition.

It's not for everyone, but maybe for some.

There's also the because it can be done factor.

I like the scheme used by Moon+ reader. It shows a count of screens instead of page numbers. For novels where there's not usually a need to make references this seems nearly perfect.

It can show the number of pages in the book and the number left till the end of the book like this (152/42) or it can be chapterized and show the number of pages in the chapter and the number left to go. It also gives a percentage for the book. This is the method I use.

A page of course means a screen full of text. Change the margins or line font size and the count changes. I rarely change these things so I'm getting constant and accurate information on where I am and how close I am to the end of the chapter. This lets me keep reading if I'm near the end of the chapter instead of stopping when I get the urge to stop.

I don't like 1 screen = 1 page because it can change. It's not something you can look at and get a sense of how long the book is. ADE page numbers let me get a sense of how long the book is. Also, sometimes I may change the font size and in that case, I'd also be changing the page numbers.

I'll admit it was a bit odd not to see the page number change all the time, but I got used to it and I don't mind it at all. In fact, I do like it. Sometimes the page number jumps and skips showing a number. Again, you get used to it.

I also prefer page numbers to not be screen numbers, but I understand why others may want that instead. It would be nice if readers had a choice.

Sure, and there are plenty of hw/sw combinations that do just that, except on non-jailbroken kindles.

Some people are in book clubs, which migh want to reference locations in novels, so standardized page numbers have uses, even in novels.

If your current system meets your needs, good for you.

I thought I was used to amazon locations, but I'm starting to get spoiled by "real page numbers". I see nothing wrong with good enough getting even better (without ramming anything down people's throats).

I think they (at least somewhat) do. For example, the (ancient) pb360 images in post #1 are showing screens and pages.

They do now. ePub with ADE page numbers or KePub with 1-screen = 1-page.

It would be better if format didn't determine that choice, especially when "choosing" ePub to get consistent page numbers means you have to sideload.

I like the idea a lot. I haven't had much luck experimenting with your files yet, but I may have gone through them too fast. On my PaperWhite 3 I haven't been able to find an .sdr folder (does this require jailbreaking, or am I'm just blind?).

Anyway, in my opinion (for what it's worth) this would be the best solution I've seen for page numbering. And I want to look at how you use AsciiDoc for this (in your provided source files), as I've used AsciiDoc for a little website and I like it.
