my friend and i were going to study a language together and wound up having to cancel our plans due to scheduling pressures, but! through research we came across a really cool resource for reading in a TON of languages: bloom library!
as you can see, it has a lot of books for languages that are usually a bit harder to find materials for—we were going to use it for kyrgyz, for example, which has over 1000 books, which was really hard to find textbook materials for otherwise. as you can see it also has books with audio options, which would be really useful for pronunciation checking. as far as i can tell, everything on the site is free as well.
Checked it out and the catalogue is great for Indonesian and German. Not much for Japanese and for Korean it seems to be all in the category of spiritual at the moment.
