@templetongate @bookstodon Going on a not great memory, it could be a Kindle indexing problem, might try re-starting the Kindle. For Calibre definitive answers, try https://www.mobileread.com/forums/forumdisplay.php?f=166 ,all the devs hang out there. Ask questions with good explanation and all pertinent data and you will get great answers.

@demerara @bookstodon Thanks. I'll check that out when I get the time. I have re-started the Kindle when I added 20 of the earliest titles I had obtained, but Calibre only recognized 12 of them. Thinking it could only do a minimum number at a time, I deleted the others, rebooted, then added only 5 back. It's not recognizing those 5.

@templetongate @bookstodon What format for those 5? Which Kindle model? What OS? Is Calibre set to auto-convert to that device? Any errors reported? Can you restart in debug mode and see what the log says? Can you see the books with your file manager?
I haven't really used my Kindle for years, since I got a #Kobo, but with data like that the folks at Mobileread will know what's what. I know I've seen this question asked there, but can't remember the answer!

@demerara @bookstodon I just signed up over there but don't have time right now to post my questions. The titles I added are .mobi I assume, or maybe prc or azw, not sure, but the same as the ones I was able to add to the library the other day. I have a Kindle Fire HD8, which is about 4-1/2 years old. My computer is W11. I can't answer your other questions until I get some more information.

@templetongate @bookstodon OK the Fire is not a Kindle, it is a tablet (Even Amazon doesn't call it a Kindle anymore). That takes it totally out of my own knowledge.

@demerara @bookstodon But Calibre is supposed to work with almost any device, not just dedicated e-readers. An iPad is a tablet which Calibre says the app will accept, so why not a Fire tablet?

@templetongate @bookstodon Oh Calibre will work with a Fire...it's just that the question posed baffles me since I have little to no experience with the foibles of the Fire. A book that refuses to go to a device can be caused by a multitude of problems...in the book, the device, Calibre settings...a wide field.

I purchased Vellum software a couple years ago, and it works very well for creating ebooks. If I'd known more about Draft2Digital at the time, I'd probably have just used their free ebook conversion. They'll work with a Word file, and they make it easy, easy, easy.

@lauramh @templetongate @bookstodon I had not heard of Draft2digital; that looks like a pretty good service. Vellum does make some very pretty books.
But as an old geek I don't like the code it produces. I have only one eye I can read with, and it is none too good, so I edit nearly every ebook I read to make the code dead simple so I can expand it a LOT and still read it. Vellum and other tools make that tough. #Ebooks could be more #accessable, but many are not...

@demerara @templetongate @bookstodon I'm impressed with your knowledge of code. I'm clueless in that regard. D2D is now doing paperbacks in addition to ebooks. I'll probably try that out for my next novel. They partner with an audiobook company, too, but that's pricey.

@lauramh @templetongate @bookstodon Just read your Shinbone Lane teaser. Code is just knowledge, like maths, but writing like that is a real talent!
