#epub. A good thing: officially standardized by the W3C https://github.com/w3c/epubcheck . However, some auto-generated epub seems to be rubbish; 3 out of 4 of my epub readers failed to parse the epub, even after editing missing fields per https://www.edrlab.org/open-standards/anatomy-of-an-epub-3-file/ . I'm not sure how the 4th one managed it, but it's pretty ugly. Guess I'm sticking with #pdf on this one.
@souldessin I am a fan of Calibre, and have been using it for longer than I've been using Linux! But how do I get it to clean things up?
@worldsendless
I just set my reader model in the setup and imported any epub. Then I told it to convert and upload.
@worldsendless what are you doing with epubs? I use them for reading novels, but that’s about it.
@writh yeah, an old book from archive.org. Done right, epubs have certain advantages over pdfs. But apparently they can be done very wrong...
@worldsendless
Check out [Calibre](https://calibre-ebook.com/). It will rectify any issues in an ebook to be perfectly compatible with your reader. I use it for a bunch of auto generated books from online.
