Sorry If this is not the right place to ask, but If I wanted to grab all the information and data I can, in case my country decides to start blocking out internet access, what are the must-haves in regards to offline data?

So far I've only downloaded kiwix and corresponding Zim files for wikipedia, wiktionary, wikiquote. My internet download speed is already slow but I want to download things while I can. Thank you, and sorry again if this is not the right sub
