What is the original, first printing, date the book was published?
Check the book you want to review. Look at the title page, or the backside of the title page. What is the earliest date you see? Look for the earliest date the book was published because that is likely when most of the reviews were written.

If you cannot find the date, check the book title in OneSearch and see what year the book was published.
