As far as I'm aware, there is not way to directly do that. My recommendation if you're really concerned is to take screenshots of each page. It's pretty quick if you do it on PC bc all you have to do is shrink the page until it all fits, then hit windows + print screen, and then click the next page. You don't even have to move your mouse. It wouldn't be too bad to automate it either. You have 2000+ plus marked, that's like 200 to 210 screenshots, which doesn't take up too much space. Just put a YouTube video on in the background and go to town lol

Is there a way to download the whole list of read, to be read, on hold of what I have? I just heard the news of another website that just went down…I just wanna keep my list downloaded for the future just in case.
