This is super timely — looking forward to take a look at this in the evening. Wish this was in an ebook format so I could stick it into my Kindle and read it that way though. You might want to check out Calibre, it's an app that automatically converts to more ebook-friendly formats. Might be worth a shot.

BTW - you might want to just host the PDF on your website behind an email wall and put it behind Cloudflare. I just spent 10 minutes trying to get the PDF, it's that busy on Google Docs.

Edit: I just tried to convert it, it works okay, not super great, since the source is PDF. I'm sure you have the raw text document, you can flawlessly convert from that to EPUB/MOBI if you want.
