Polish books for everyone in pdfs = wolne lektury
I don't know if there is a similar topic here on forum but if you are looking for Polish books to read for free try something Polish for children...
You can find a choice of books there [not only Polish] in pdfs which are obligatorily in Polish schools [we called them 'lektury'. Each child must have read them :) I think there is an app as well but I have never tried it... wolne=free, lektury=school books
Do you have anything similar in your language? Just paste a link below...
I am interested especially in languages I learn in Duolingo. Thanx
Usually in Polish schools you have got a list of books you have to read. I found this website a while ago and I use it to download and read my old books from school. I hope it will be helpful
In English there is Project Gutenberg. Free books in the public domain, many of them required reading - Jane Austen, Dickens, etc. I believe they might have texts in some other languages too such as French.
In Russian there is lib.ru.
In Japanese (in case anyone is interested) there is aozora bunko.
Projekt Gutenberg: about 8000 books/stories in German http://gutenberg.spiegel.de/
another site for free audiobooks in German https://www.vorleser.net/
Just a warning - these are books in a public domain, which essentially means they are not the newest ones. Some might use somewhat old/archaic version of a language.
Except that - a great resource and if I recall correctly many of those have also audiobooks so you can listen to the real life language.
