PDF's to study 118 different languages
I got this from a brazilian website so the name of the languages are in portuguese, but feel free to ask me the translation, or just go to google translate. I don't know if all the languages have pdf's in english, but the ones I saw did.
PS: I got this from the facebook page of Universo Racionalista. https://universoracionalista.org
There's no Maltese though.
I opened random pdfs for 'ingles' and 'russo', and the text in them was all Portuguese.
