I only read one of them in fact. Wasn't aware there were more. Will check them out today ;)

I think what you are doing is a great idea and I did consider putting the PDFs on the steem blockchain but didn't like the idea of turning each book into a post, which would involve lots of copy/paste. And the formatting would likely look weird. Better if I can upload the actual documents, which the LBRY blockchain permits... once I update my OS.
