I first tried to setup the download automatically, so that I can trim it down to get what I wanted. I had some issues, but that is not the point. I realized that it was completely wasteful to do the full download just because it was possible. I found that going through the list and pasting the 2nd URL to a browser and manually getting the books I wanted worked great. I got most of the maths and stats on the list, some QM and some in other topics that interest me. I a mgrateful for this. I encourage you to not be wasteful either, and not download 450 books you will not end up reading.
