Hide Pages in MOBI (urgent)

Evk · 10-25-2021, 02:25 PM

Hi all,

I'm working on creating my eBook and I need to hide some pages (a kind of internal wiki) from the eBook index.

As I have verified, on MOBI the "linear = no" tag does not work, so I need an alternative solution to hide these pages from the eBook index.

I hope for your help.

Do you mean that you do not want this content to appear in the linear progression of the book, only if the reader explicitly jumps there from elsewhere? If so I don’t think that you can do that. The best you can do is put it at the end of the book.

If you mean that you don’t want it to appear in the table of contents then that is determined by how the TOC is built.

You may want to look into a Kindle feature called X-ray that allows extra information to be added outside of the regular content of a book. Amazon describes it this way: X-Ray is a unique Kindle eBook feature that allows readers to learn more about a character, topic, event, place, or any other term, simply by pressing and holding on the word or phrase that interests them.

See the KDP help topic X-Ray for Authors for details on how to generate it.

There is a mobi (KF7?) specific HTML "no next page", so that later pages are only accessible via a link or TOC. I forget the syntax.

But it's now pointless because if you have a later kindle that does KF8 and/or KFX, then Amazon might not preserve it on conversion. Also you can't (allegedly) upload mobi to Amazon now. An epub upload to KDP is recommended with docx second best.

Summary: maybe 10 years ago for Kindle and Mobi only it was possible, unlikely now.

I was going to use it for a "plot your own adventure" back in 2012, but I'd do iOS and Andriod apps for that now, not even epub3.

As far as I know, there is effectively NO WAY to do this in Kindle format, whether we're talking ePUB, MOBI (now outdated and no longer uploadable), or KFX.

The syntax is: <mbp:pagebreak crossable="no"/>

As you wrote it is effectively useless since it only works on the oldest of Kindle devices.

Well, Diap and I both still have K2's, (as collectables, effectively, rather than eReaders that we actively use), so that's two devices where it would work.

I have a feeling there's a lot more mobi-only kindle devices still in use than many people seem to want to believe.

You know that we always, always, make a build inside the files for them. I have now and it still works. My theory is, as long as mine lasts, it is foolish to think that people are simply chucking them away for no reason.

That's exactly the "command" I was thinking of.

It does work on the DXG, which they were still selling when PW3 came out, but only batches of old stock. But I never tested it on anything else.

I'd assume it works on any kindle that can use a KF7, maybe all of them? But you can't upload it to Amazon.

I have a KK3 that was my son's kindle, which has the last FW for it. It renders KF7 nicer than the DXG and I wonder did it always have KF8 or did it originally only do KF7. It had older FW when I got it, but I don't think I checked it before updating it. Within limitation of 167 dpi vs 300 dpi, it seems to render KF8 more accurately than the PW3. The PW3 image size bug has been mentioned before.

I haven't kept up with the nomenclature of the various Kindles, but if one of those K's in KK3 is for "Keyboard", then KF8 support was definitely a later addition to that device. It was pure, old-school-mobi-only when it was released. It even predated the "KF7" terminology.

KK3 is Keyboard Model B008, between DX (B005) and DXG (B009). The Touch was next model. FW 3.4.3

I think that though the DXG is later than KK3, it's really just a DX with a better screen, thus likely not enough RAM etc to run later than 2.5.8 FW
Amazon don't even call the DXG (B009) with better screen a later gen, it's lumped with Gen2.

We have one Basic model in the family that's not a Paperwhite, but has better than Basic 167 dpi screen. Like a PW3 screen with no front light.
