Where can I buy this book?

On Amazon as a print-on-demand paperback or an offset printed flexibound (recommended).

What about a digital version?

This is planned for publication on Amazon in September ’26.

What are your credentials? Where are you published otherwise? (19.04.2026)

              Finally someone bothered to ask me a question – thanks. I have no other publications in English (and nothing relevant in Polish). For information about my credentials, please see the ‘Author’ tab.
