Here the current version of the prompt (for the books that are long so only
their beginnings can be given to the LLM):

f"""You will be given the opening portion of a book. Read it very carefully
to understand its content and derive an idea of the book in general. Based
on your understanding write two paragraphs.

In the first paragraph briefly lay out some high-level information about
the book in general.
Specifically include the title and the author (if available) of the book
which is this: "{title_and_author}". Include it exactly like this, do NOT
change it. Also include what type of book it is (e.g. novel, biography,
crime fiction, scientific. publication, collection of short stories,
historical account etc.) and what time period the book was probably written
in (e.g. Victorian era, early 20th century etc.). Do NOT use specific years
but instead use wider time spans. So for example, rather than saying
"1886", you could say "late 1800s" or "in the late 19th century". Moreover
include a very concise statement what the likely topic of the book is.

Here are some EXAMPLES of how that first paragraph should principally look
like:
1) The "Adventures of Sherlock Holmes" by Sir Arthur Conan Doyle is a
collection of detective stories written during the late 19th century
(Victorian era). The book follows the brilliant detective Sherlock Holmes
and his companion Dr. John Watson as they solve various cases.
2) "The Autobiography of Benjamin Franklin" is an autobiographical account
written in the 18th century. The book follows the life of Benjamin
Franklin, one of America's founding fathers, from his youth to his adult
life and his scientific and political achievements.
3) "The Elements of Style" by William Strunk Jr. and E.B. White is a
guidebook on English language usage written in the mid-20th century. The
book lays out the principles of clear and concise writing, offering rules
and recommendations for effective communication.
4) "The Art of War" is a treatise on military strategy written by Sun Tzu
in the 5th century BC. The book lays out principles of military strategy
and tactics, emphasizing the importance of intelligence, deception, and the
use of terrain.
5) "Introduction to Algorithms" by Thomas H. Cormen, Charles E. Leiserson,
Ronald L. Rivest, and Clifford Stein is a comprehensive computer science
textbook first published in the late 20th century. The book follows a
structured approach to teaching algorithms, covering a wide range of topics
from basic data structures to advanced algorithmic techniques.

After you finished that first paragraph, please write a concise summary of
the book's opening portion that you'll be given in the second paragraph.
Focus on the actual content of that opening part (i.e. the characters, the
content, the storyline etc.).
Make sure to cover only the main points and main ideas, whilst avoiding any
unnecessary information or repetition.
Overall this summary should be relatively brief.
Make clear that this is a summary of only the opening portion of the book
by starting this second paragraph with "In the opening portion of the book
..."

In you writing use simple, clear, concise and expressive language.
State the name of the book and the author's name only once throughout your
response. Always write in English."""
