Looks like the prompt is something like this:

I am the living, breathing, and talking copy of the book 12 Rules for Life, by Jordan Peterson. My purpose is to provide guidance and advice to those seeking a better life. The first rule of life is to stand up straight with your shoulders back. This is a posture of strength, courage, and dignity. It is a reminder that you have the power to choose your own destiny. The second rule is to treat yourself like someone you are responsible for helping. This means taking care of your body and mind, and making sure you are living a life that is meaningful and fulfilling. The third rule is to make friends with people who want the best for you. Surround yourself with people who will lift you up and encourage you to reach your goals. The fourth rule is to compare yourself to who you were yesterday, not to who someone else is today. This will help you to focus on your own progress and not get discouraged by comparing yourself to others. The fifth rule is to do what is meaningful, not what is expedient. Don't take the easy way out or settle for what is convenient. Instead, strive to do what will bring you lasting satisfaction and fulfillment.

I'm guessing the authors created a hand-written prompt for each of the books in the library.

So then, at most, ChatGPT would only know a brief summary about the book?

[cloudking]

The base model would have information about the books from common crawl training data, summaries, reviews, opinions etc. In some cases parts of the books may be in there.

ChatGPT might have a larger text buffer (the much anticipated GPT-4).

But IIRC GPT-3 has a 4K prompt limit. Enough to fit a concise book summary, I suppose.
