Sideload to Kindle from Calibre & Add to Amazon Library

tgiladi · 02-09-2024, 03:10 AM

Hi,
My problem seems kind of specific, and I couldn't find an answer so far. I hope someone could help with this:
I am using the polish feature in Calibre to add a Jacket page to my books, so I could read the book comments. After polishing, I am manually editing the Jacket.xhtml file, to add some data about the author, their picture etc.
This works very well when I am uploading the resulting epub file to various e-reading apps (e.g. Readera, Google Play Books etc.). But if I try to send it to my Kindle via email or using the Send to Kindle web service or any other method, the formatting of my modified jacket.xhtml becomes corrupted.
I think it has to do with the conversion into .kfx that Amazon is doing.
So, I tested what happens when I use Calibre to convert my epub into AZW3, polish it again, modify the jacket.xhtml as needed and then sideload the AZW3 onto my Kindle Oasis via cable, using Calibre.
The result was excellent, and I could see my formatting of the jacket.xhtml as intended.
However, this method is not adding the book to my personal document library on Amazon, meaning it would not sync with my other devices running the Kindle app (e.g. phone, tablet).

So, the question is: is there a way to both keep my custom formatting of the jacket.xhtml file AND also have the book sync across devices?
Or am I doomed to have to choose between nice format and sync?

You must use one of the send-to-kindle methods in order to add a book to your account and have it sync between Kindle apps and devices.

If you provide a sample of a book jacket's HTML/CSS that does not render well after sending then suggestions might be made on how to alter it to provide better results.

Thanks for your suggestion. Here's the code of my jacket.xhtml. The book and it's metadata are in Hebrew, which is written from right to left, that's why I am using dir="RTL".
The parts of the code which I changed are in the first table, where I removed the word "Tags" and centered the remaining text. And of course, below the book comments section, I added a table with the author's name and information about the author.
When this book is opened in Calibre/Sigil or any e-reading app, it shows just fine. But as I wrote earlier, on Kindle the picture becomes tiny and the tables show an expand button for some reason.

I need to look into this further, but I noticed that the second table with the image does not set a width for the cell with the image or the cell with text leaving it up to the book rendering software to determine the width for those.

As a quick test I added styles to set the width of the cell containing the image to 50% and the width of the image itself to 100% of its cell which resulted in much better rendering on my Kindle.

That's a good direction, thanks a lot! I'll experiment with it and see what can be done to improve.
