I've installed KOReader in about 3 devices but I haven't yet cracked how to keep them all in sync - frankly, I don't know how the syncing process works.

I used to think that it syncs up both the books and the reading progress / metadata but when I tried doing it, it didn't seem to work that way. I would love to hear how folks have done this. It's about the only thing left that's keeping me from using KOReader more frequently on all my devices.

I manage my ebooks using a self-hosted instance of calibre-web. This allows me to sync my library to my Kobo e-reader using KOreader. Also, turning pages is faster than with the stock reader of the device. https://github.com/janeczku/calibre-web

OPDS (Open Publication Distribution System) is protocol in the background. Jellyfin has a plugin for OPDS and works by simply dropping a file in specified directory, but it doesn't support multiple catalogues (i.e. one per library/directory).

Protocol is atom based, chatgpt was able to make a custom OPDS server for my needs within minutes, it took another hour or two to fix and customize generated code.

Earlier quoted context omitted.

I tried koreader on a kobo. I wouldn't call it trivially easy when I installed it last year, and I promptly uninstalled it and removed all the hacks so I could get back to a sane installation of the Kobo OS again. I think maybe for a kindle it might be worth it, but the reality is for Kobo, it's probably more hassle than it's worth. I found my time better spent setting up a calibre-web in a docker container and then…

What's the issue you had? When you reboot or quit you're kicked back to regular Kobo and you open up Koreader through a menu option. The Kobo OS is good enough for me to recommend it to family, there's nothing wrong with the iPod experience of uploading books. But Koreader+Tailscale+Kavita OPDS is the best reading experience I've ever had.

I don't remember frankly, maybe something with the script, maybe something with KFMon. Lack of integration with the Kobo OS itself? Maybe it had to be rooted to install KFMon, but I was reading Koreader could just run inside nickel menu maybe? But yet the script installed KFMon?

Again, I don't remember. And whatever it was it's not worth me trying to reinstall it just to remember what it was, and then to uninstall it again.

Can anyone recommend a site for buying DRM free books so I can read it with KOReader?

https://www.libreture.com/bookshops/ has a list of stores (and for Norwegian books there is https://ebok.no/ ), but I have found no way to search "globally" (across sites like that) for DRM-free ebooks.

https://news.ycombinator.com/item?id=32442549 has some more tips.

Oh and https://bookshop.org/beta-search now actually lets you check "DRM-free" when you search, which is a very good step in the right direction!

I have a dream of https://news.ycombinator.com/user?id=marginalia_nu taking up the mantle. Though I think anyone could make something that's better than what we have now, which is nothing.

I've purchased a lot of mine from Kobo. There's also Standard Ebooks if you want free, high-quality reproductions of public domain works.

Note that with Kobo you need to check. I bought one there once thinking it was DRM-free, it was not.

The progress sync is separate from how books get onto the various devices (at least as far as I know). Something OPDS capable works well to get the actual files across a network (or calibre via usb). For progress you can use their provided sync server or run your own (the original one gave me enough trouble to write my own implementation).

KOReader is an amazing program that has progressed at amazing speed over the past few years, particularly when it comes to the user interface. (It can still be overwhelming, because of the sheer number of features, but it is much better organized.) To give you an idea of how different it is from commercial products: it actually tracks reading in a useful way. It shows a chart of how long you have spent on each page,…

> If you want to read a multicolumn paper on a small screen, you can configure it to go down one column then right back to the top of the next column. If you want there to be overlap between the screens when panning, you can configure that. You can also have it display which parts were overlapping, so you don't get lost when it displays the next part

That's insane, I thought it was already good with a whole page, I will have to explore this more. Might need to update it as well, since I installed it a few years ago.

It was the only thing I could find that works well on a Linux tablet. Other readers have poor controls for a touch screen.
