I bought "The Reasoned Schemer" as physical book and searched for a way to buy it as a PDF version, but could find it nowhere (also had no problem to pay twice for the book).

The Kindle version of it does not even have fixed table cell width for the layout of the conversation.

German book website buecher.de has "The Little Learner" to preorder as ePUB with Adobe DRM. I don't know, if you can buy digital books on this site outside of Germany. Also notice, that copy-protected digital books on this website are highly unusual; most of the books are with watermark instead, if at all.

I have no clue why a book with pedagogical background and custom layout, has copy-protection and no print-quality PDF version (but instead one with poor layout).
