No, there is no harm asking. If you could see that stuff online, I'm sure someone here would know where to find it, so you asked in the right place.
I would offer to send the book to you, but it weighs about 20 pounds and it would probably take $39 and 6 months to get it to Poland (if it ever arrived). By then you'll be finished with your thesis and working on the crew of a whaling ship in the Sea of Japan somewhere.
I can't offer to send you scans because I never scanned it. I can't scan it. A) I'm afraid it would break the scanner glass and injure my small dog, and B) whenever I open the book I immediately fall asleep. It's the damnedest thing.
So I'm sorry. I want to help, but I can't.
