i shouldn't be required to convert my books to a proprietary format in order to read them. i also have some epubs that have issues when being converted to mobi or azw3. issues as in they can't be read on the kindle after being converted even though they are read just fine in calibre. if they would just support epub then this wouldn't be an issue.

They are adding epub support this year https://goodereader.com/blog/kindle/the-amazon-kindle-will-s...

the article you linked to literally says that's not the case. the way it works is that you upload your epubs to amazon and then they convert them from epub to azw3 for you and then allows you to download them to your device. not only is this a rube goldberg machine that doesn't support epub, it's been unofficially possible for years already by changing the extension from epub to png to trick it into thinking it isn't an epub when it is.

One important caveat in the article:

> Update: It looks like Amazon is converting the uploaded EPUB to KF8 (AZW3). So, it looks like they might not support EPUB natively.

It's a mass storage device. You should be able to plug it in and copy files as normal.

The problem is that many PDF's are simply a bunch of scanned images. And these can't be readily converted to any text based format.

The exception is to put the PDF through an OCR process, but this destroys the formatting and can't deal with images. The whole point of my scanning these old books was to keep the historical information.

I have hundreds of old books I have scanned and converted to PDF, but I cant read these on a Kindle.

what did you use to scan them? did you have to remove the binding?

I have various book scanners. eg a Plustek Optibook 3600 which has done an incredible amount of work.

Plus I've built a dual camera book scanner similar to https://www.diybookscanner.org/

And where necessary I have access to commercial high-speed duplex scanners which do require that the spine be cut. OK for old magazines, etc.
