A comment on sharing files: if you want to share an electronic copy of a book (or article), I'd check if it's available on Library Genesis or Sci-Hub. If it's not on Library Genesis, it'd be good to upload it there and share with others
they offer a guide on how to upload/share too. I don't think Sci-Hub is adding new materials at this time though.
Below are two links to Anna's Archive (a book/article download aggregator), from which you can choose a site to download the PDF without needing to sign up or login to anything:

I posted two as I see they are from different publishers, in case that matters.
