Troubleshooting Books not showing up on library (but they are on device)

doedeer · Yesterday, 10:13 PM

Over the years I have sent hundreds of books to my kindle using Calibre. Usually download .epub, add it to my calibre library, connect my kindle via USB and then convert and send to device. Lately, when I send a book it doesnt show on my kindle's library. If I use the search function, I can find them and read it, so the conversion and connection went fine, it just doesn't appear in the libary.

Some things I tried:
1. restarting my kindle.
2. converting to azw instead of mobi.
3. many different files.
4. deleting files that show on my library, and then re-sending them again (they don't show).

I'm using Calibre 6.7.1. I have a 6th gen kindle paperwhite (Firmware 5.12.2.2), it's been on airplane mode for many months now.

There's no need to use MOBI on anything except a very, very, old Kindle. Your default format should be AZW3, and/or KFX if you add the KFX Output plugin. I'd go into the device settings and uncheck MOBI. (Plug in Kindle, let Calibre detect it, click dropdown next to the icon in the tool bar, select configure this device, uncheck MOBI from the formats listing) AZW is just MOBI with Amazon's early DRM. AZW3/KF8 is a newer and much better format, and KFX is even newer.

Thanks I think that partially fixed it. Now the books are showing in my library, but when I sort by recent (my preferred method) they are not on the top of the list, as it used to be. I have to sort by author and find them on the author.

If your device has been in airplane mode for a long period the internal clock may have drifted significantly. That can affect the order in which books appear in the library.

Also be aware that enabling WiFi after a long period offline may cause sideloaded books to be deleted from the device.
